I logged in via email, and I got nickname idchlife530425d9f7554e76, but my real nickname is idchlife
But my old profile, which has the same gravatar - https://online-go.com/player/449218/ - does exist.
I created it for about half a year ago.
For some reason system did not logged me in but created another profile. So every time I log in now - I log in in new profile, not old. Cannot access old profile
