This isn't a paysite.

What this user has done is post furry artwork on Tumblr which is what a lot of furries tend to do in their spare time.

What this user has done however, is create links that go through www.linkbucks.com . Even though it says allanalpass.com it's still hosted by linkbucks (to make the URL more appealing). Essentially, clicking on that link will show an advertisement from linkbucks, that will allow the person to navigate away in 5 seconds (what you see up the top right) while the advertisement shows in the middle. The advertisement however that linkbucks is showing is from a malicious advertiser, and tries to get users to install that executable which is obviously a trojan horse as it's trying to deceive someone to install it.

So once the user gets past the advertisement trying to install that shit on their computer, where does it navigate you? Right back to that Tumblr page. That's why all the source links are the same, it just leads back to that Tumblr page, and with each click on those links that are hosted by linkbucks, that person who owns the Tumblr page gets a small amount of money. The reason all the links are the same is when people on Tumblr share that Tumblr post, when people see that shared post on someone else's Tumblr page, they click the original source link so they find that original Tumblr page and also give that user money.

In short, it's not a paysite. It's someone using www.linkbucks.com to earn money by having people click on the source links leading back to their Tumblr page. Linkbucks is showing malicious adverts. The user is a cunt.

Hope that makes sense.

Oh yes, as for a means of stopping this, you need to go through Tumblr. This is the result of a Tumblr user, not that website you thought it was.

You can use this to try and complain about the blog not being flagged for NSFW (I don't believe it is, might be wrong), and for posting Deceptive or Fraudulent Links for the source of the images, as they aren't the original source and they use an advertisement service to get through the links.

For actual copyright takedowns, the artists need to do that themselves as outlined in that link I posted from Tumblr.

Thank you Synx. Will file complaint via that tumblr community link.

That tumblr is now deleted.
Was hoping that they would just delete the spam links.

Unclear to me whether it was a furry's blog or just a spammer who saw a niche to profit from.

NSFW blogs are fine as long as they're labled NSFW. I don't believe that was. Combined with those deceptive links that were giving him profit, I wouldn't be surprised if that was the reason.
