I like this idea, though it should likely be a challenge clbum and could never speed run.

Attacks could be timed or be related to lurking.

-Attack “Send Private Message” player send mysterious private message

-Attack “Barge into conversation” user acts like he knows what is going on

They could use the same slots as permanoobs and pwn forums by staying there for extended periods of time, such as having an attack that says move to next thread
