Looks like calpsy2 is saying he made a post in
this thread and the OP of that thread (BeastBTC) hacked his account and edited the post and changed it to a vouch for his service.
Calpsy2 If that is true then that means BeastBTC probably has the password to your account, as he didn't get in via email or security question, so change that password anywhere else you use it.
I looked through your posts and it doesn't look like you posted a Bitcoin address. Did you ever PM someone one? if you did there is a small chance you can claim your account back by sending theymos a signed message from the address and telling him which PM the address is in. If you didn't then low chance of you getting the account back.
BeastBTC was selling combo's here
https://archive.is/VzUj5 so he probably has a leaked database from some bitcoin site and got your password from that.
