I'd be fine if people signed up with these to try it, but they should use a permanent address if they want to continue using it. I would have no sympathy at all if they lost their account.

Fair play. I suppose the key thing is I've been able to strike up some really good relationships with users and customers by knowing their email addresses - but clearly users of throwaway email accounts aren't going to be open to that kind of communication anyway.

Mainly I've noticed a distinct correlation between spam signups/service abusers and throwaway email accounts.
