I was on here a lot way back when, I stopped using it for while, went to log in and found my password didn't work, and when I tried a reset it didn't go to my email. Anyway it can be returned to the original email address? I'm guessing not, but thought it was worth asking, especially because I figure the only reason for people to still an old account on a board like this is to use to scam people.
What makes you think that it was the Russians who hacked your account? If someone is doing posts in Russian now, it still means nothing. It is quite possible that he was hacked a long time ago and now they simply sold it to someone. In any case, you need to contact Meta with this problem.
