You can't be too hard on the seller, the muppet has had a "we need to check your login details" email from "eBay" and given some scammer his login details and they are now using his account. Hence why the auction asks for you to email
gogu_pintenogu00067@yahoo.com for info. One hopes he will be getting onto eBay at to report that his acocunt has been hijacked. Its not like there aren't stories about this kind of thing on the tv, on the news, online, in emails from eBay/your bank/etc telling you not to give any of your details out, idiot.
