I don't know if this is the right board for this thread.  If not, please make a suggestion and I'll move it.

I sold some BTC to a couple of Kenyan scammers on Localbitcoins.com.  I verified their IDs, and everything looked cool, so I followed through with the transaction.  They used credit cards to pay through PayPal.  One of the scammers wanted a lot of bitcoin, but she could only send $50 - $100 max, so she submitted 11 transactions.  Like a fool I just went along with it.

Several days later both of them submit disputes, they even submitted multiple disputes for the same transaction.  I wasn't able to respond to the disputes through paypal's web interface, so I called them.  I sent an email to them with all the receipts and transaction communications that I downloaded from Localbitcoins.  They reversed one of the transactions, but all the rest are going against my account.

Yesterday I got an email saying I need to pay that money or it will go to collections.  I don't have any sock puppet paypal accounts, this is my legit account with my real name, bank account, credit card, and SSN attached.  I don't feel like I should be held accountable for this shit!

What can I do?  Thanks for your help.
