Neighbor of mine put one of his apts up on craigslist for a weekly vacation rental. He gets a reply and sets up a 2 week deal for $2500.00. They send him a fake money order through the mail for $5k asking him to send back $2500 because they over paid.

Do these idiots actually get people to fall for this shit? Why the fuck would they spend that much time and energy trying to do such a stupid ass scam.
Not to mention it's now a federal offensive if they are caught, because they attempted fraud via US postal service.
