Scam Alert Network?

Something as simple as a mailing list might work, but it needs to be somewhat exclusive.  Otherwise it would give the scammers valuable information and defeat its purpose.  It could share critical information such as compromised account numbers/addresses and known aliases.

I'm thinking it should be mostly for exchanges, markets, stores, or other entities which sell a large amount of Bitcoins.

Could be abused to blacklist people they don't like.
