I used to get emails from Jock2Go in my spam, and figured they were connected with RM.
Friendboy.pro (fka Rentboy.pro) had a reputation of creating ads for providers without their knowledge, then contacting them with the news, and I assume put it upon the provider to accept or not, or to do with it or not, I don't know, I'm just a client. I've been distrustful of Friendboy for that reason. Would hate to blame a provider for inaccurate info it's not the provider's fault.
