He signed a 2015 one, he obviously needs to get his account back. This forum cannot let this sort of injustice happening, it's really nonsense, considering it takes a minute to reset the password to his requested email. Theymos seriously needs to hire staff to get this done faster or if someone gets rejected, at least explain why and don't let the guy waiting infinitely.
I think some kind of automated system has to be created for this purpose. It's not that hard to implement a bot with the administration permissions who will be able to receive messages from people in some format, check their info, signed messages, etc. and send links to reset password to their emails. It'd be much easier and faster than it is nowadays.
