I wouldn't hold out hope for recovering your old account. I'll give you a merit to help get you started fresh.
Take more proactive measures to not get hacked again.
Stake a f'n address.
I know, I should have, frankly I had no knowledge of that address staking topic before that... Thanks though, it warms my heart. but I just can't let it go, I knew I should have changed my password after Bitcointalk database hack, but I did not. And that's my cross to bear
Thanks again

Also, OP claims there was an address under his signature which was deleted "years ago" which he could sign a message from. In 2014, 2015, 2016, it appears to have only been "have a nice day!" in the signature (
reference), sometime in 2016/17 it changed to an address - the same time it became branded with this "Luxury" marketplace that this person is now hoping to use to recover the account... I don't think this account is going to be recovered anytime soon.
I'm not even sure that there was my btc address under my signature, more likely under "Bitcoin Address" on my profile, it stayed there for a while, but then I assumed that it would make me a target for hackers, so I changed it to a bogus address, and of course, that's the only screenshot Web.Archive has >>

Although there might have been an address under my signature at some point, I have never thought of using wayback machine to prove my claims, maybe if there was an address under my signature at some point I could find using wayback machine, thanks a lot for the idea, I'll try and wayback each and every message I ever wrote, even if there is a slightest chance that I could prove my claim.
Bottom line is, I won't let that go, even if it's the last thing I do, that old 2014 account has way too much sentimental value to let it go, I'll do whatever it takes.
Hey, I even contacted the UBEX ICO's team so I could track down and email whoever is using my account now and buy it back from him, turns out he never claimed his tokens so they don't have his email address in their XLS payout file. Another f*n dead-end.
I have also conducted business through my marketplace with an old timer member (
https://bitcointalk.org/index.php?action=profile;u=162183 ) who could assess my story and also has my bitcoin address but everything went through gmail, so that's another dead-end I guess.
Wish me luck I guess ... Any other ideas/inputs would be greatly appreciated.
