You're right to be cautious, I was attracted by the chance to exchange comments with some of my favourite pornstars.... as it turns out they'll thank you for a tip, but there won't be any chat. And then I was billed three times over two days by a performer I had never heard of. When I contacted the company they ignored my first two emails and then told me after the third email I was going to be banned for making false allegations. I had already cancelled my membership by then.
