This goes in the hall of shame.
There is only 1 safe practice.
Sell,take money out of bank.
When i do a transaction, 1000+ , i have the wife,who works downtown in the same building where my bank is, go down and withraw the money and deposit it in my checking.
If they file a dispute,Paypals going to have to take it to court, which they do not want to do. In court, IP information can be obtained, which usually screws the scammer. IP info can be subpoenaed from Blizzard as well, showing the IP address where the accounts were logged in at.
But hey, if you are the OO you got nothing to worry about.
