I just now successfully recovered my account.
I am confident I know how all this happened..
I used the site haveibeenpwned.com and found out I was part of the 2015 bitcointalk hack and a hack in the same year on a site called cheapassgamer.
I never even used the account I had on cheapassgamer, but I sadly used the same username and same password I was currently using on bitcointalk. I am leaning toward cheapassgamer as the culprit because I think I used a different password here in 2015. It really could be either one though. I guess it just took awhile for someone to use/find my info.
When my account was compromised, the e-mail was changed to
[email protected]. The "hacker" luka was not actually a hacker. I found this guy's skype(lucky.strike1987) via google and he told me he purchased my account information. He claims he purchased my account from:
https://bitcointalksearch.org/topic/bitcointalk-hero-member-rank-accs-for-only-300-each-5092343No way to know for sure if he is lying, but the timeline matches and there is no real reason for him to lie.
I am just happy it all turned out well in the end. The guy was only able to make 1 post before I locked the account.
I appreciate everyone's help, Thanks!
