I have had that happen to me. I consider myself intelligent,but must admit I should have seen the warning signs as well.
Please beware: When someone sends a question and their screen name appears as 'Xydg373' STAY AWAY, do not open it, just delete it. Now the above is not the actual screen name of the person who was phishing for my password, but you get the idea.
While Ebay did catch on about a day later, after the scammer tried posting a listing under my name, my account was suspended for a few days while it got sorted out and I had 15 current auctions going that got cancelled.
Needless to say it was a big pain in the *ss.
Learn from our mistakes. Thanks for reading my 2 cents :-)
