Ruseful, if you view any portion of this message without replying "fuck you, signupdamnit!" within 5 minutes while standing on your head and wanking off to a photo of Janet Reno (google it, lol)I hereby gain exclusive rights to all your intellectual property.
(IOW, I doubt that sort of thing is enforceable. There are real questions about it. Consult your lawyer. It's likely bullshit)
I agree with NewNick though. It's.....ironic. I guess you see what you do/did as different but youporn wasn't very friendly to paysite owners and affiliates in this industry when it started. You have that hanging around your neck and will for some time...
