> @troyhunt: It has my email address – I get email by sharing it with people who might want to send me email!
This is golden. Hilariously incompetent tech support trying to make someone delete the tweet complaining about their spam.
It's similar to advice for "forgot password" forms not to acknowledge whether or not an email address or username actually exists--simply tell the user an email was sent for that account regardless.
It is indeed very difficult to keep ALL your email addresses from being publicly listed, so I use GMail accounts for the ones plastered all over the web, and let GMail handle the spam.
