I (try to) block all throwaway mail providers, but give users the possibility to delete the mail after confirming the account. Then I keep a salted hash of the mail address for 6 month to deny another sign up. Only reason being spam protection.

I love places that don't block throwaway mail providers, cause I really don't want to enter a real email address at every random site. But if I had a site that had a lot of users, I'd probably want that because it would automate many account maintenance issues. I have started thinking my main privacy issue is the phone company tracking my location all the time and then selling it to anybody in the world, and me not being able to do anything to block that is the real issue (short of getting rid of my phone).
