Delete account

I've been thinking about this, and for that it worked there should be a system that detects when a user that has been refered by another deletes account, so that that referral doesn't count, so that the user looses his referral.

Don't know if I expressed myself clearly but the idea would be to not let have suddenly 100 deleted referred users and then after a time have to pay for them.
