Scammers are trying many different things.
Another email to keep a look out for is a fake "Receipt for Your Payment to ......."
I got one back during the summer. I clicked it and it looked just like any other of the emails I get after I've paid through Paypal. The problem was it was thanking me for sending something like $465 for buying a Nokia cell phone. It included an ebay auction link to an actual auction for a Nokia cell phone with a "buy it now" option of $465! There was another link on the page to dispute this charge. After clicking this link it wanted my social security # plus all my account info. At this point I knew something was wrong.
I contacted Paypal by phone and was told no charge was actually charged to my account.* They also told me to send the email, and the auction link to
spoof@paypal.com. They sent me an acknowledgement email and said they would look into it. I have heard nothing else since then but I've been getting 3-4 emails a day supposedly from Paypal wanting me to update my records. I was sending them to the spoof email address for them but I got tired of it (didn't seem to be stopping them) and just delete them now. Looks like I somehow got on one of the spammers email lists.
* I also contacted Discover, the credit card I have my Paypal account tied to, and there were no charges placed on it.
I've got just over 200 transactions on ebay with Paypal plus other uses (like here on CD

) and haven't had any actual problems with Paypal yet. You just have to look out for those fake emails.
