SCAM ALERT: I’ve gotten this message several times now:

Dear eBay member!

Your information in our eBay file, was marked (flagged) as incorrect and/or (fraudulent). To avoid any inconvenience concerning an interruption of your service membership, in future. Please take just a moment and update your eBay billing file. Remember to “doublecheck” all the fields for any possible mistakes.

There’s more, with a link to a page where you can enter the information. Except that the page has nothing to do with eBay, and the message (though it appears to come from eBay) actually doesn’t if you check the headers.
