I've seen/read too many request to recover their account in this board and this example is the worst for almost a year without being recovered and noticed by the admins.
Theymos said he's working on an automatic recovery tool that should be ready before the end of the year so you'll likely have to wait for that
Hope it will not reached until 2020

Only if the admin can implement even at least a confirmation email/message once a person change the account's password or email. Most probably it will lessen the numbers of hacked accounts.
