Has this ever happened to you on eBay?

I received a message via e-mail that said "this license is not valid, please respond or I will report you". The item number doesn't match any of my recent sales, and is only 9 numbers long. To respond via e-mail, I need to log into eBay, which I don't want to do. It did not show up on My Messages on eBay. Everything else does look real though.

some other web site. I saved the .html, traced down the guy who sent it, and sent it back to him thanking
him for the eBay spam. Guy had a AOL account email. Was a nice looking spoof ad.
They will take care of it from there.
