That's awful! I'm so sorry, I thought my paypal account was hacked (was a phishing email), and I'll never forget that feeling. I hope they fix it for you right away. The people that hack other people's account are such scum.
I was gone from my computer for maybe an hour while I gave the baby a bath and put him to bed, cleaned up the toy room and I find a ebay message in my email and someone told me that someone hacked my account and was posting on the ebay boards. I guess they found the link in my ME page??
it happened to me yesterday - well last night - all day i've been changing passwords etc.... its driving me nuts! im like checking my cc balance every hour just in case - its best to be safe than paranoid!
unfortunately, since this has happened, i dont think i'll be logging on to eBay again - quite OTT but at least i can still have a look through! i'll wait for my last eBay purhase to arrive and then i'll stop bidding on things... it just kinda freaks me out and im trying to save!!!
