Nielsen Research and Ru-Kun’s 3rd Payment

Hello everyone and how is it going today? I hope all you awesome visitors are doing ok. I’m doing ok my pain levels are pretty high today but I will make it there as I got a lot of shit to get done. This blog post is one of those such things. I have another post to write as well, both are the type of posts I love to write as it’s always nice to get extra money consider most of us don’t get a lot of money or are living pay check to pay check. Now this is a payment proof post about Nielsen Research and programs like these can help out a lot of people. Now this is why I started researching and investigating programs like these where you can work from home/online or have passive/semi-passive earnings to get you extra money. Technology so much allows this with no limitations on programs But there is also room for a shit ton of scammers/scams.

Nielsen Research i.e. Nielsen Holdings is a data and information measurement company that researches what people watch, read, listen to, buy and so on. Now with this being stated, I @ru-kun have been testing out Nielsen’s mobile and PC research panel. To be fair I have tested Nielsen for sometime but less then what I have set for the testing phase of earning programs. I still made sure I got a third payment. But Nielsen is almost worldwide and has been in business for a looonnnng time, according Wikipedia (on Nielsen Holdings) though not a super reliable source, but it is correct on when the company. Nielsen started in 1923. Now as far as I can tell Nielsen doesn’t offer affiliate programs.

That being said I have no link for people to join and I won’t be rewarding any for activity on this program, This may change in the future, but most likely won’t because they been in business for so long. But I still share this with you as it could be helpful. Some people make a pretty ok money doing these programs and some people survive off these type of programs. Mainly in countries that don’t have the opportunities’ that like I have here in the United States or other countries like Canada and United Kingdom.

The 3rd Payment Proof

Now you can see below my payment proof which I had requested and was sent to my PayPal account.

Ru-Kun's 3rd Payment From Nielsen. $15 PayPal
Ru-Kun’s 3rd Payment From Nielsen.

It payment was sent to my business account to help cover web servers costs for my network. It was for $15 USD and you earn points which that can be cashed out for a payment option, product and so on. They have soooo much shit you can get dvds, fucking kitchen supplies, gift cards, books, all kinds of shit. Kind of cool not going to lie. But you have to install software on you computer and/or the mobile app on your mobile device. Then you earn points everyday when you use you device. They also have some micro tasks you can get points on their website for the mobile/PC panel.

You want to use this program you can check it out at the direct link here: https://computermobilepanel.nielsen.com/ui/US/en/sdp/landing

Remember I don’t earn anything from your traffic or sign up on the above link and neither does my website Thoughts Of Everything as my earning and site earnings are separate. Thanks for reading and stay tune for more. Got something you want to share sign up on our website to comment on this post.

Making That Extra Money Paid-to-Click Payment Processing Payment Proofs Programs I'm Testing

Sweet, I Got My First Payment From Rotate4All

Hello there everyone and how i the world are you all doing today? Hopefully all is going well. I’m not doing too bad myself though the day, I had a flat tire when I got off work at 4:30am in the morning and had to miss work the day before to get it fixed as I just bought the tires and had them fixed under the tire shops warranty due to the tires being used as I’m on budget. But so far it seem to be ok. Anyways, not lets get back on the task of this blog post.

Now, I have been testing out this program for a bit now though as with other programs that I can’t verify whether or not they are going to be a paying or scam. But this is what I/we do here at Thoughts Of Everything test extra money making programs, passive earning and so on, kind of like scam hunters but also the ones to bring the best beer money or bud money programs that can get you that extra cash for whatever. 

Now one such program that you can earn extra money click/viewing/surfing ads/websites and also earn for promoting the site’s ad rotator hence the name Rotate4All. Now they pay out through Paypal (PYPL stock code), Airtm, Skrill, Bank Transfer, Bitcoin, Perfect Money, Payeer, and Faucetpay. Now, I can not recommend the Perfect Money, Payeer or Faucetpay payment options due to those payment systems block or don’t allow users from the United States Of America. 

So, let me go into a bit about my first impressions of the site and service. Rotate4All from an advertiser stand point, though let me remind you that I have not advertised on the on the site yet but I plan on it in the future right now I just don’t have the budget. But I like how advertisements are displayed from the paid to promote options and the surf options which has a super small image kind of cheat/robot check that is displayed in random spots throughout your screen display. This works better at keeping bots/cheaters out and get real human views. Now, from an earning stand point it seem to me to be legit and both surfing and the paid to promote options can bee pretty quick it seem but you have to work hard at it or have the cash flow to purchase advertising for your links. Now from my first payment proof (remember you can click image to view full size) Now I requested and was paid through a payment system called Airtm, get an account here: https://app.airtm.com/ivt/russell0a14f408 which is being used by a lot of online businesses including my own get-paid-to/traffic exchange/and other business ventures. Now here is the payment proof screenshot.

Rukun's first Rotat4All payment
Rukun’s first Rotat4All payment

So I had requested $5.02 and the amount seen above is after the fees which are different depending on the payment processor/system you user. minimum payout is different on others payment processors as well. Either way I can now label this as a paying program as of right now and I will continue testing for a bit to give real results.

Now remember guys at the time of this post this program maybe be paying but it’s still in our Thoughts Of Everything earning program testing list. So join with caution. With this be said if you would like to test it with me and I will probably reward my active referrals but you must say in contact with me and joining this Thoughts Of Everything community can help that now here is my Rotate4All referral link: https://www.rotate4all.com/ptp/?r=MrRuste

My 11th Payment From GptPlanet

Hello everyone, how is it going with all this crazy stuff with the cornavirus and what not. Just remember common sense goes a long way like washing your hands and not touching your face.  Anyways, I will leave that for another discussion as I’m more or less here to talk about an awesome trusted site and administrator in the online money making environment. The website is called GPTPlanet which is a PTC/GPT website. PTC is short for paid to click and GPT is short for get paid to. These are site you can earn extra money from online just by viewing ads or completing tasks. GPT Planet has been online for a long time since 2010 and his other site Scarlet-Clicks which has been online since 2009. He also owns another site called Optimalbux online since 2018. So this business/network is very trusted what I would call an elite site as it even survived the big PayPal freezes where Paypal started freezing the funds of a lot of PTC/GPT owners because of all the scammers. PayPal is still pretty bad which way site used other payment processors such as Payeer (USA members not allow me included), Skrill (formally known as MoneyBookersBitcoin, Dash, Litecoin or other cryptocurrencies. With this being said I just received my 11th payment from Gpt Planet and I was paid through Skrill. See my screenshot below.

ADS By UAP (PTC site) Balance Update 1-27-2019

Hellos everyone Rukun here. Sorry again for the lack of content on the site, and our youtube channel. I’ve been somewhat active on twitter and on our Facebook page sharing stuff. The people I asked to help out here haven’t really done a whole lot yet and I’m thinking they ain’t going to do anything,  prove me wrong guys. LOL Anyways with this being said I’ve been thinking of content to add and because I’ve been busy trying to open another PTC site for my network with low payout with cheaper ad prices and values to make for fast clicking. Anyways, back on track here. So a while back I wrote about this site and said it is in my testing list and I haven’t been too active due to a problem group of people in the industry which I’ve been working on solving as well, but anyways ADS by Ultimate Affiliate Program (UAP for short) is the program I’m talking about. It’s a paid to click site or PTC for short. For me the only option is payouts with Bitcoin but Payeer, SolidTrustPay, and Perfect Money. I can’t currently use those 3 payment processors as Payeer and Perfect Money don’t accept USA members. And for some reason SolidTrustPay isn’t registered in my state. Stupid as it hurts business and Paypal like to be stupid to PTC and GPT  or other online earning sites. Sometimes I think I should just create my own payment processor XD. Anyways enough chatter here is my screenshot of my account balance thus far on Ads by UAP.

If you would like to join click this link: https://urle.io/adsuap-referlink and go all the way through until you get to Ads by UAP as you supporting this site by not only signing up but clicking through the link.

Thanks for reading as well. If you sign up as my referral you REALLY should join this site if you haven’t done so already. Thanks.

Living life with limitations and pain This IS Not Right Work Life

Sometimes You Got To Just Step Outside And See The Big Picture

Hellos everyone, Ru-Kun here with what is going to be a more serious post about some pretty serious subject matter and this is just what I currently going through. First, I want to say this issue or situation has being going on for over a year since transferring to this store that I currently clean at for my job.  First off and I will probably say this again later on in this post but I have never been more thankful in my life than I am now considering the shit I’m dealing with.

Bullying and discrimination happen all the time and everywhere. It’s a big problem in society and I have never knew how much of a problem it is until the current situation where I’m having to test myself in keeping cool. Maybe, it because of all the bullying I had gone through in my life. I didn’t have as many friends for the longest time and was picked on during most of my school life. But throughout my life I have made some good friends that I would never have been able to get through everything I have gone through in my life. When I think about that I get sad as I then think about those who don’t have what I had like close friends and good people around me and are struggling with bullying. But still continues because of fucking societies bullshit of that is how life is. This time in the work environment, not ok. Dealing with for over a year. To top it off I’m damn disabled from a car accident though not labeled federally still in pain everyday. But I work pretty damn hard that half of the healthy people I see out there cry over a headache. Stupid shit

So anyways further details to the life of Ru-Kun follow post of message me LOL I have more people supposed to be write for the site but they haven’t posted shit yet. I just more or less want to be thankful for being as blessed as I am and sorry for those who are innocent. The thing I’m thankful for the most is my old boss who was the regional manager if it weren’t for him being my boss for the incident I was involved in I would have never had back-up or a defense for the issues as it involved racism and it would have messed up the rest of my life seriously. So this is where I’m coming close to need to get a different thing. Though, I would rather doing my own thing which thoughts of everything is included but I’m in the process of the start of that with as I got part time work at my buddy’s awesomely yummy pizza place.  Best damn pizza in Spokane, Wa Market Street Pizza Parlor (click here for Facebook page) if your local come in. And if you visit from out of town come in great family pizza place and hand tossed pizzas’, brink oven cooked get your ass in there. I get more hours that way and I wold like to see it go big and I want to be part of that depending on future plans. I only get part time  Thank you Market Street Pizza Parlor owners, you guys have been my friends for a long while and also thank you my old boss. You will know who you are as I will share this post with you :-). Anyways, I just wanted to be thankful for all those who have blessed my life including my future wifey.

Thank you for reading  and also thanks for clicking on the Facebook link and if you liked awesome now come in and eat visit Spokane for this pizza LOL Thanks LOL Have an awesome day.

The Beginning Of Investigating Paypal, PTC and Frozen Funds & the Honest Businesses

Well hello readers and visitor, Ru-Kun here. I’ve been planning to write this post for some time now and I still really don’t know how to approach this. Maybe I should just keep going in guns blazing. So first for those that don’t know Paypal is a payment processor used by a lot of online stores, shopping carts for customer to make a purchases. Or Paypal is used for sending money as well to other users like friend’s and family. A lot of people use and trust Paypal. Maybe too much?? Well that is what I’m going to find out. I’m going to investigate why Paypal has frozen the funds of so many business owners. I have been using Paypal for a long time and  have a verified business account. Heck this site uses Paypal for donations/life time full access this site.

Anyways, I’ve kind of been talking with some get paid to admins and some of the things I’m hearing is like how in the heck does companies like Paypal get away with freezing peoples accounts and not communicating. This hurts us all especially the members who had done work or purchased somehting from the site.

While I look into this further I’m kind of thinking of a way to help honest people/business owners to recover their fund from PayPal. Maybe some sort of legal help.

What do you guys think?

Thanks for reading.

CTFO CBD First Testing, Kicking Things Up Notch

Hello readers, members & visitors. Before I begin talking about Changing The Future Outcome CBD products and the program. I’m going to have to give you some background information on myself and the pain and limitations I have to deal for the rest of my life. Some of you may already know my background. But for the new readers or visitors I was in a car accident back in 2012 where I was hit in my park car with hazard lights on. Just out outside Spokane/Deer Park area in Washington state, USA on highway 395. Upgraded members only get major details about my accident since I settled rather then fighting due to over-stressed, depression and life issues. Dealing with all the bullshit that comes with people’s opinions like like you pain is in your head and mean up shit got to me as well. So now in a sense I’m really suffering because of it but I’m thankful for all the things I have to help be less uncomfortable. Medical cannabis and CBD has been my major pain relief since 2014 because I have a lot of issues with nausea then finding out it helps with a lot of other pain as well. I have a medical cannabis card but at the moment cannabis is not completely legal at federal level which I have never wished prohibition of cannabis to end more then ever now. Which is why Thoughts Of Everything will be looking into donating a percentage of monthly earning to help push the legalization of cannabis. CBD is mostly legal but still has the stigma attached to it which I’m at the point that it needs to end. Anyways, so anyways, I’m looking into the CTFO which stands for Changing the Future Outcome that has a line of legal CBD products for multiple things such as pain relief and help to get you some sleep. You can either sign up as an associate and sell the products or purchase from me.  There is NO THC in CTFO and is cruelty free. Also once I get all the eggs in place for how to help end cannabis prohibition 1% of my CTFO earnings will be donated to the cause while the other is going to help cover cost of Thoughts of Everything and helping me with my health issues from my car accident. So to start I had made my first ordered for Full Spectrum CBD Oil Drops – 1500mg and I’m starting my test. Runs about $99.99 and I believe is the highest strength offered. I use CBD concentrates as well from my local cannabis store since my state it is legal for the most part. I plan on ordering some other things and since I’m almost out of the previous CBD cream I was using before (Non-CTFO).

Anyways so far it seem to help but because my pain levels the recemmend doesn’t last all day and I’m probably going to have to add other CBD products as well.

If you would like to order CBD products from me with NO THC click on the shop link on my page here: https://myctfo.me/rutakus/ or if you would like to sell CTFO products click on the opportunity link on the navigation menu.

Don’t forget to register for an user account on Thoughts of Everything so you and I can work together and either help you find the best products for you or help you gain a downline or make sales leads.

Thanks for reading.

So as you guys can see I have be posting a lot of new online earning sites like PTC sites and what not. As I’m trying to kick off my ideas for mu business and because I like to research and investigate things online earning sites are first on my list of investigations as with the amount of scammers in the world especially online where people become even more fake. But even though there is a lot of scams a I would like to make a change on the online earning community but I’ still trying to figure out my plan. I know I normally use paid to sign up offers to do new earning sites but there isn’t many trusted site in my list at the moment. Even then there is not always a guarantee someone will buy PTSU credits for advertising. So I sign up on this site without using PTSU. The site has both Paypal and Payeer for payouts. Paypal, Payeer, and Perfect Money. Again I can’t use Payeer or Pefect Money as I live in the US. Anyways, I will post more updates when they become available.

First Payment from PolicePTC and Second Payment from Paidtoclick.in


Well I’m now glad to say I have another PTC web site I can add to the paying list. Though on the paying list does not mean they are elite or trusted. But PolicePTC is now on my paying site list with one payment thus far. I wish the PTC world wasn’t so untrusted. But thank you PolicePTC  admin for paying and working hard to keep your site going. I know as myself being a PTC admin as well with all the scams out there it makes it really hard to make it. So good honest admins need some extra praise. PolicePTC currently only uses PayPal but Bitcoin coming soon. So this being said here is my first payment and proof from PolicePTC.

So just before I received the payment from PolicePTC I also got my second payment from PaidtoClick.in(NOW A SCAM). This is nice but I have a slight issue with one of my purchases on the day before Christmas where I purchased a featured link and it hasn’t been approved yet. I sent many emails and contact form submission (screenshot each one). I’m at the point of filing a Paypal dispute for my first time to get them to approve my l,ink or refund my money. Hopefully this doesn’t cause issues. But here is my second payment screenshot.

Life with pain and limitations

So first this is going to be a multi-post meaning it will have more then one topic. This is because I have a lot going on and I kind of need to write as well for more then one reason. First I posted my job blog post on this site in the Craigslist resume section to one increase my views and also start trying to get a different and better paying jobs that cares and works well with person’s with disabilities as that is what I am. Here is the Craigslist posting: https://spokane.craigslist.org/res/d/about-that-time-to-get-better/6701339654.html I’m only looking of work in the Spokane, Wa US area unless remote work is available.  Also I wanted to state that soon I will be having a premium member access and payment options soon to help cover costs of running the site and if I run into any issues with my posts. Although, I do my best to be right in that I as well as the site never intent to harm anyone but in some sense people do it to themselves and what goes around comes around is what I truly believe and maybe it is because of some of the things I have seen throughout my life.

Anyways, so today I’m in a lot of extra pain and it hurts like hell. I don’t have my actual medical records available at this time to give you guys what is actually going on but I will say I have bulging disc from my neck down to my butt. and some compression on my annular cord in my thoracic area. Today it really hurts at times to a point it makes me want to to give up as it so unconformable and makes it hard to move. And let me put it this way. I work 47 hours a week on average and one day off a week. This is part of the raise I want a different job or where I’m making enough running my own company I don’t need to work for anyone else. Right now I’m trying to make it and deal with it as much as I can. All this shit because of a car accident and now I have to deal with this for the rest of my life. I am thankful for the amount of tools and medicine have available and the help. Thank you for reading my complaining. Today is just one of those days where I’m in a lot of extra pain.

Life Surprises Me All The Time, But Not Always Something I like, Damn Human nature

Most of the time in life I’m usually pretty easy going and was more so before I had got a major injury that has affected the rest of my life. I was injured in a car accident with FedEx and to this day I regret settling my case instead of going full force law suit. But the amount of stress and the extra bullshit from the  case and my own legal team that I actually still have stress issues and anxiety and anger with. But I know for what goes around comes around. I will never stop believing that as I’ve seen enough in my life to know that it does. Anyways, so I was hit by a FedEx van that was going 60 mph on Highway 395 just outside Deer Park, Wa heading into Spokane to go to work at Walmart on north Colton in the city of Spokane United States. I suffered multiple bulging disc from my neck down to my lumbar spine. This happen in 2012 and I still have issues to this day and it’s never going away. But I’m doing my best to manage my pain and doing pretty good for the most part. But I have a bulging disc in my neck, I think like 2. I have 2 in I think in my thoracic spine with some slight compression on my spine between T7=8 and T8-9. I also have some bugling disc in my lumbar I think one disc is slightly degenerated. I would have to look at my MRI stuff. Anyways I might go more into detail about this later on in a later post of something.

So as you can see I have a lot of issues including a degenerative eye issue called keratoconus which I had all my life pretty much. Basically I don’t have as good of vision as most people. You could say I’m pretty damn disabled and yet I fee and have bee told that I work harder then most healthy people. I’m in pain all the time but do my best to maintain it. But its not always possible especially when your like me and work a crap ton of hours. I’m pretty much working overtime most of the time since Black Friday of last 2017. So I work a lot of hours for a company called Kellermeyer Bergensons Services where I’m a Crew Lead in their janitorial area of services and have been for a while now. About a year and half. I also run my own business since 2010. It doesn’t make much money but it starting too and trying to kick it up a notch. I have a 4 year degree, majored in Software systems engineering and minor in business management. But I have issues sitting for long periods of time now because of my car accident injury. So I don’t really work in my field of study except for my business. And I am getting management type experience from KBS (short for Kellermeyer Bergensons Services), but my experience working for them hasn’t always been the greatest. And by next year I’ll be making minimum wage again for boss work. I have asked for a raise many times.

LOL I’m always looking for the better opportunity here is my current resume located on my own secure web server for the most part ran by me with some limitations of root access: https://cdn.rutakus.net/resumes/Russ_gen-resume2018.pdf
