I stumbled upon this site today, a very useful collection of the usual suspects. Hopefully the author will continue updating the list as more of our enemies reveal themselves.
The author, Dia, says: These are a collection of people I've met, or stumbled upon rather, that you should be wary of. They are proxies, revenants, puppets, corpses walking, enough kinds to make your head spin. Then there are simply the ones that know too much. Anyone I list here, watch them closely if you run across them. Or, if you are wise, you will run the other way.
