You guys are funny. Let me help you. I have about a ebay rating of 500 and paypal rating of 200. This is how you use paypal/ebay.
A) Whenever your selling intangeable goods AKA UO account DAOC account SB account. You sent out something through fedex. I use a letter that states the account name/pw. This gives me backup and makes the good tangiable. When someone files a compliant via paypal they ask for shipping #. This gives me the shipping # so they can't recall the money.
B) I don't really use paypal for any payments over 350.00 for this reason also. Use western union. They pay the fee's and you get cold hard cash. Always get all personal information always.
C) I am sorry you guys got fucked:( Make sure when you are dealing with alot of money you know the in's and outs. I can help anyone who wants to know more info.
PS- I own obi.
