One sad side effect of the internet being so cheap to use, is it means scammers can scam at the speed of spam. The specific case is the fake "Ebay second chance offers." Luckily ebay makes it really easy now to see offical messages from them, so you don't have to find that one line that makes it the scam.

EDIT: that's number 3 of the fake second chance offers on the same item.
