Link: https://bitcointalk.org/index.php?topic=1935179.msg53648750#msg53648750I myself got my account back after a long time!
I gave up on him, after it was captured in 2017...
But since I was a silent reader here from time to time, I coincidentally found an interesting forum post after long time:
https://bitcointalk.org/index.php?topic=5089878I still had emails with 1on1 the same content, that I had saved here in my inbox.
This makes it comprehensible!
I also tried to add all possible infos, which came to my mind...
Apart from that, the team can probably identify or narrow down, whether it is actually your account by your logged IP address in past.
At least I got a link in the meantime where I should verify my IP.
And then, almost 2 weeks after my first e-mail, I received another e-mail with which I could take possession of my account again!
There are still miracles... I hope you get your account here back, and your other accounts as well. Good luck...
