I'm not sure PayPal closed your account because you received "dirty" money--if they had any suspicion about where gameristo got his funds, I'd think they'd close his account before he could send you anything and wouldn't penalize you instead.  That makes no sense.

As I said, I got a warning from PayPal about using the F&F feature instead of Goods & Services, and that was after gameristo had sent funds unsolicited to me, which pissed me off.  I don't know what's up with him, but perhaps he'll see this thread and reply here.  Again, I've had no problems with him other than getting PayPal funds prior to any deal being made, but if my account (that I've had for years) were closed because of it, it'd be a different story--and I understand your frustration.
