...no idea who's fooling who, but basically this site is where people troll chatrooms to bait paedophiles.

http://www.perverted-justice.com/ where people have baited peodophiles into actually meeting up, and then waited for them with a baseball bat or similar. They will also put the victim's pic online, contact their employer, etc....
Not pretty, but some might say it's fair enough....though personally I think I'd rather see the law sort it out properly and convict such people instead.
