Facebook, LinkedIn, Twitter and any number of smaller social networks we don’t even know all seem to suffer from the same problem: ignoring the fact that domains cease to exist.
Only just today, I’ve spotted mail from LinkedIn to many accounts in over a dozen spamtrap domains. Twitter likewise, and Facebook, even more. I imagine that having control of these email addresses, I could “reset password” in all of those accounts if I wanted to, and therefore gain control over most of them (if they aren’t using two-factor authentication, such as that LinkedIn offers). How is this in the interest of the social networks or the account owners?
