what would probably be the best way to do it, is to start with "block all" then when you browse the forum, see people who you know are friendly or you chat with through im or chat rooms, you do invitations, like a buddy list. then when you go through the pm system, it will say at the top "X want you to be on their buddy list, click here to see list" then a simple yes/no next to it so it can either add or just stay blocked.
so say for example over a period of a month you *should* have the relevent people who you would wish to talk to and then over time you build from that.
