In warez scene paysites like yotta, affcash and many other websites offer so shitty services when members after purchasing want refund money? This is shit. Do you ever saw members area? When visitor spent 90$ (when think that he spent only 3$) and got utorrent.exe setup with comments "use it for highspeed downloading" that's crazy

only usenet websites offer really true download service and maybe some other web based download websites.
So when we talking about PPS or revshare - it is impossible to get revshare when users after first 5 minutes in member area want refund their money.
