Well to be fair, most websites are subject to phishing and scamming. I had a BEAUT claiming to be from amazon last week (which I forwarded to them - I always do that), and in my time I've had loads from ebay, paypal, play.com (who have sadly shut down and been taken over by the evil rakuten !) And I can't count the number of times my bank accounts with Barclays, Lloyds and HSBC have been hacked. I am never sure how that's supposed to happen, given that I have never had accounts with any of them....
We should simply all be aware that there are scammers out there, and take sensible precautions. I think it's rather unfair to pick on ebay as a prime sinner. They do warn everyone to be careful - but so few people bother to READ security pages. The bad guys are the scammers.
