Ehhh...Quickseller comes to mind immediately.
This is a nice idea, sort of, but it's what we have the feedback system for. A thread with listing scammers as its goal is doomed to fail, because it'll become a spam thread with people arguing back and forth, and it'll quickly become disorganized. You'd have to manage it like that "known alts" thread, where there's kind of a spreadsheet thing. And, as Vod alluded to, you'd need decent evidence that someone is a scammer. That's the argument I've read on bitcointalk many times, why admins don't ban scammers--because it's too hard to prove.
But hey, good luck if you can get it started.

LEDGER....
