Posted this in the other thread, but I'll add it here too.
I would keep an eye on the sponsor accounts that were killed. Not accusing anyone of anything, but I can remember when I was heavily involved in anti-piracy that sponsors would kill an account when called on it, only to redirect to another account when the heat was off.
Then there are the sponsors that totally don't give a shit. I can remember going back and forth with Score Cash about sites like
http://directbigboobs.net that steal tons of big tit content, including Score Cash's, while flying Score Cash banners all over their sites. I was told in so many words to go fuck myself, which is why for what it's worth I won't promote them anymore. It's pretty tough for a legitimate affiliate to compete with a site like that. No worries, I'm glad to not have to deal with the headaches anymore...
