I received this email from ebay telling me that i have not paid yet for an item i won...some 20GB harddisk...When you click the link to pay for the item you get into an ebay lookalike website except that the address is not ebay.com but something like ebaay.com which can fool many people around. Of course you type your username and password and then the phisher will use them on the real ebay site.
So open your eyes for email like these especially for those, who like me, use ebay a lot.
