I call this the "problem of trust" and it is something I'm trying to solve. In order to be able to send out alerts, we need some sort of decentralized broadcast system. I am developing a P2P broadcast system called Proofnet which is based on proof-of-work to prioritize messages and minimize spam. I have describe it on the Bitcoin Forum here:
One of the applications of Proofnet is a decentralized web-of-trust where you can send out a scammer alert by giving someone a trust rating of 0 and broadcast that message with very high proof-of-work. See some more info on those efforts here:
