I had a rifle in the FS section that got bumped a couple of times. Every bump the same person would PM me with some lowball offer. I guess he didn't pay attention to the fact that I had already "no thanksed" the previous offers. It's one thing to set a negotiation range. It's another to be insulting.

I kinda like the "no criminals" stipulation. Bet that stops all the bad guys in their tracks.
