I wonder if that explains why I suddenly started getting spam at the addresses for my LJ accounts?

Thank goodness I use Sneakemail; different email address for every site/account, so all I have to do is a couple of clicks to disable them, and generate new ones. (No help for putting the horse back in the barn, but I do highly recommend Sneakemail for folks who want to avoid this sort of problem in future.)
