I think they wait for them to actually see the message on the site. I'm not sweating it. If the guy sends the money any time soon then I won't care.
But if the shit list doesn't work, I'll harass paypal and get his paypal shut down. If that doesn't work, I'll go to visa or whoever did the transaction. He should have just kept his word and refunded it. I'll make this guy get a new identity if he doesn't do the right thing. The client already gave up on me so I got nothing to lose anymore. I'm pissed about that but that's my fault for trusting this jerk. If I don't see the money in my account in a couple weeks then I'll start my own scorched earth policy with the info I have.
