My account was hacked recently too. Luckily, since I have been here for years, I have BTC addresses in several threads, some of them locked (so the hacker could never edit them). And I could sign any of them.
I already sent proof to Cyrus a couple of days ago and now im waiting. I have objectively speaking all proof needed to prove the account "manselr" is me, so if the admins are legit (and I don't have a reason to think they aren't) they will recover my account (hopefully it doesn't take ages, because verifying the signed message takes 2 minutes to be honest). I will just wait, but im sure I will get it back.
