They don't do it just in the slave/master section but through PMs as well. I've lost count of those who PM me "wats ur asl", "ill b ur slave", etc. And the worst thing is that if they took a minute to check my profile, they would know all the answers they're looking for... I even had different signatures saying that I have a Master & received PMs from guys asking: "Is it true or you just don't want to be bothered?"
I've got to think like Strawberry & say that they're probably trying their luck regardless of who they send a message to or the title of threads, in that case.
