Detecting throwaway email addresses during registration (infosec.pub)

Spammers, trolls, and ban evaders often use temporary email addresses. PieFed now checks a list of known temporary email providers and displays a warning icon next to registrations that use such services.

If registration mode is set to "Open" (no approval needed) then the site admin(s) receive a notification instead.

A throwaway email address isn't always a bad thing but it's one factor that admins might want to take into account.

Throwaway emails seem kind of necessary on small, underdeveloped, easily hacked websites.
