After a few months of serious brainwashing (by me

), a friend of mine once tried to buy a Scope card, but lost to a last-minute-incredibly-high-bid on Ebay. A couple of days later, he got an email, from the supposed "Seller", saying that the highest bidder couldn't pay, or something to that effect, and if he wanted it as "second chance offer", for the bid he had entered. He said OK, but then they sent him a fake Ebay e-mail, with a fake direct link to a payment procedure via Western Union. They also asked for a lot of personal info - and that was what gave it away. Had he not confirmed the e-mail was false (by forwarding it to spoof % ebay.com) he would have posted the cash out to somewhere, and never get anything in return, and the worst thing is, those @!#$*! bastards could do this over and over again.
And this was not just a case of getting the most out of a bidder - they actually faked an e-mail that looked like it was from ebay, with the logos, the fonts, the color schemes, everything, and they provided false links to proceed to payment, even claiming that it was all under Ebay supervision.
So, remember, second chance offers and best-offer messages you get on Ebay should also be in your Ebay-account message box. if in doubt, forward any suspicious e-mail to spoof % ebay.com, soon enough you'll know if it's legit.
An remember the most important thing about Ebay - don't go crazy! (I know I have...

)
And as skwaks said, communicate!!!!! After a while you'll know what to believe in
I myself have made excellent deals on Ebay, and never had any problems with Paypal, ever. I once got ripped off when I bought what should have been original Waves plug-ins (this was before the iLok thing), and instead got a CD_R of warez... But, although Paypal and Ebay said there was nothing they could do, they did provide me with a link to the FBI's anti-software piracy page, and through there, I was able to get the knowledge I needed to CALL that bas#$&rd on the phone in the US and make him return the money. Yes, he got scared, and gave it up, but if he hadn't, I don't know how i would have solved it.... I mean I am in Europe and he was very very far away.............. but my e-mails can be persuasive, and the timezone difference worked to my benefit, as I called him after lunch and has was still in his bed, probably dreaming of greater scams to pull! HA! B%$t#rd!
