You obviously didn't visited too much sites, or don't know how they do it. Which is cool, you are in safe waters
I saw CS on almost EVERY site, from WBB, to WJ. Specially on those small unknown DLE sites.
Well, he isn't banned because no one reported him.

Else, there would be no top 100 in that order.
For filehost, that is loosing money. For other affiliates, it's unfair game.
I guess if they have trained staff who would investigate only that, they would save piles of money.
Top 3 earners are selling 50-100+ accounts a day.Ever since playsonic exist, they are having same score. While for the rest of us, sales vary, for them, they aren't. I find that very interesting, that their market isn't already flooded with premiums. And I basically can't explain how they can possibly do it, without cheating.
EDIT: if you want to ask me why I haven't reported them, here's the answer: I don't care for other sites, except seeing that on WJ.
