I am surprised that in his research, the author didn't come across any warnings not to sell Bitcoin on Ebay. This is pretty common knowledge these days.
I was also under the impression that PayPal does not allow selling Bitcoin or Bitcoin hardware. This transaction should have been stopped automatically, and it's a shame Ebay doesn't have automatic tools to stop blatant abuse of their own policies.
Ebay could easily put their own auctions up for bitcoins at 200% of current market value, then simply cancel the accounts of anyone who bid on it. They'd hit 100% fraudsters.
