I was also contacted by eBay today. My account had been frozen because of the same problem.
eBay did not contact us. We called them to report fraud. Funny thing was the orders did not appear anywhere on the legit account (ours). We got emails that said they were from eBay confirming the orders and ups tracking numbers. eBay brushed it aside. They did not care. All they wanted was for us to forward those emails to spoof@ebay.com. I wrote the tracking numbers down and went to the ups website and sure enough, they were real tracking numbers. Got delivery status info, time the packages were to arrive etc. And arrive they did! A refurb computer and a Russian guitar.
