For those of you who use eBay: Recently, I got an email that looked like it came from eBay. This email said that my email address registered with eBay had been changed. It looked exactly like an email would look if you had actually changed your registered email address. Very deceiving. Do NOT click on the link. If you are not sure, go directly to ebay and check your personal info to make sure your email address on record has not changed.
I got about five of those recently, including one that looked like it was sent by Paypal. All are sophisticated scams and have to be reported to eBay immediately.
