You're fucked basically. You're going to have to pay it out of your pocket. My irl friend got scammed like this for I believe $70 or something? He spent it and then got charged back. The PayPal had a lot of information on it so no way avoiding it.
Remove as much information off the PayPal account as you can and don't log back onto it would be a choice but I do not recommend it. You can get into some trouble legally. Also, I'm not sure if it would break any Sythe rules.
No man theres no way you could get out of this problem.. Unless you proved to PP that you didnt authorize that transaction as much as possible give out your best to prove it!
What PP account is that so you can help out the sythe.org community and it wont happen to some users here! Thanks and hope the best for you man!
and for that guy who says change your information.. dont do that dont be stupid, they can still track your old address if you change it to a new address and your IP + your bank!
It happens in paypal and just try to resolve it!
