Someone is using paypal scam

[iTzDavid]

Okay well this guy paid me 25$ to level him up in a game, which I did.

Now he is filing an unauthorized claim. How can I prevent him from scamming me?

Can Paypal please check the IP he sent the money from? I bet it is the same IP address.

These are PayPal community member forums, so we cannot check the IP you requested.  You will need to file a dispute via PayPal with the buyer.

Same thing happened to me, a person bought an WoW account from me for $900, I gave the info, all is well, then after I even got the check from paypal for the month in my hand, that same person claimed unauthorized claim, so paypal WITHOUT ANY EVIDENCE, gave the money back to the person, telling me I owe paypal, since I am now in the negative, and the case was closed within like... 3 hours, of the buyer's claim, all this happened in the middle of the night! Paypal basically fascilitated the theft.
