I just received 3 'unauthorized' disputes today from Paypal and 1 chargeback since my last post this morning.
It's total scammerville on ebay and Paypal. I feel bad for all of the sellers there right now - if you are selling anythign bitcoin related you will get scammed. It's not even a "cost of doing business" which is the usual warning to ebay sellers... it's a total outright scamfest.
Even filtering for ebay accounts that were over 1 year old and verified paypal addresses in the US, I got scammed. This last scammer had an ebay account that was open in 2004 and verified paypal account. Learned my lesson, again.
