this guy stole from my friend and tryed blaming it on me so were were thinking of posting his number in craigslist fo a sex ad. any better ideas?
Karma. I wouldn't do it. Eventually he'll get what's coming to him. And posting his number on a sex ad could get you guys in trouble. I remember one time someone posted a teachers phone number on 4chan and he got in trouble by our local law enforcement. Lucky for him the teacher didn't press charges.
He blames you for something you know you didn't do. So you post number on craigslist possibly screwing yourself legally, and setting him up for rape. Yeah, that seems totally fair.
Send a High Times magazine adressed to him, like it is a subscription. Probably fucks up the relation with his parents xD And then subscribe him to those free porn-toys product magazines, vacation magazines (I signed up my friend once. Every month he got a big box of crap), folders for AA-meetings, folders for the army, folders for gays etc. Ah I'm cracking up. I did that to one of my enemies when I was about 13-14 years old. He got in so much crap with his parents xD
