I don't get all of the people saying OP was so in the wrong. Sure he gave money to someone he didn't know, but it's not like it was to an anonymous Nigerian prince who needed the money to gain access to his fortune, it was a public figure (to use the term loosely), a professional (again, using the term loosely) who gave them a quote for services to be rendered, albeit through Facebook, and he didn't deliver. Then Dred basically gloats about how he isn't paying them back and he didn't do what he was payed to, the dude deserves to be shot down. The amount of money doesn't matter either, whether it's a hundred dollars or ten thousand, it's about the principle of it.
Also, about BlackNerd's diatribe about getting dirty yourself when trying to drag another through the mud:
1) Dred doesn't seem to be so big that he's on all these lists and he'll always get work no matter what people say about him, the guy is begging for money to buy an iPad, as far as anyone can tell the only people that have ever hired him for anything is Sony. That's his one claim to "fame" and he should be more wary about messing it up.
2) I don't think Camjo thinks of himself as some big shot with a reputation to lose here, I doubt he has to worry about getting laughed out of every thread because PaRappa stole money from him and he made a thread about it. And if there was company that dug so deep as to find this little ordeal, they wouldn't be say "Hmm, when he was nineteen a small potatoes rapper stole a hundred dollars from him and he was upset... NEXT!"
