online pedo-bating is old hat. What I've discovered works best is a 2 or 3 man team. Search CL for horny old men and respond to them. Tell them you're 15 after a bit, like after you get them all worked up and horny for your tight teen asshole and how you just looove giving rimjobs. Agree to meet them somewhere at night, like a park or some shit. If you have a female friend willing to pose as the teen, all the better. Either way, wait until he shows up and basically mug him. Steal his wallet and make sure he knows that you have the chat logs and his information and if possible, his license plate number. Force him to drive to an atm and empty his account. Threaten to take him directly to the police station if he doesn't think he needs to cooperate.
In the end, everyone profits. You come away with money, and the community is hopefully saved from one more potential pedo. For added measure you can always threaten to turn him in if you ever find out he's doing the shit again. Tell him 'you'll be watching.'
