I never made a signature because I didn't understand anything about it.
There is a huge post gap between October 10, 2014 to February 25 2017 and most probably there is a chance of change in hands between the same time. Although, the email address doesn't seems to be changed as per
bpip.
I see you have no crypto address posted before 2014, there is even a password change on 2018-08-06. I would suggest you going with
recovery team. The account is banned for now.
Also, please move this thread to
meta section, from the left bottom of this page by clicking on move topic. Suits better there.
