Sounds like morroco.man or one of the other PayPal scammers. They're pretty poor and will scam you the first chance they get, even if it's only for a couple of bucks.
He will be back with another alt to get you guys again. Hopefully you won't be dumb enough to fall for the same thing twice.
PayPal email address is the same as his contact?
The thought of someone scamming for $100 though is pretty sad.
I mean I guess this adds up since if he does this x10 times with however many alts he has.. then thats damage. I just wish there was a site that collected everyones alt that used for scamming.. its kinda hard to follow alts.
