If BF's posts bother you so much, go get 20 of your buddies(or fake nicks) and each of you post a "See Sig" pic in every thread. I can't see it lasting much longer after that. It would ruin the board.
Alternatively, put him on ignore and generate some traffic and send it to BrokeAmateurs.com, GirlsGoingSolo.com or PureAshley.com.
