You can't help those how can't help themselves.

I'm for a scammer committee.  Two or three trusted member or maybe more then you have an x of y votes to apply the tag.

Some guys can be VERY aggressive.    I know I jump the gun on occasion.  But I think it would work pretty well.  I would also put the community on notice that their trades are being policed.

We would also have to define SCAMMER.

My opinion it is a person who does not uphold their end of a deal after a period of time.  The scammer thread it a place to publicly debate it and if the scammer make good the tag gets removed.

I DO NOT think welshing on a bet is scamming.  So after the whole MNW debacle, even those he's an cocky arrogant asshole, I don't think he was a scammer.  But the scammer tag did seem to silence him.  So that was a good thing.

Just my 2c
