My two cents ... As far as I know, Theymos personal data is not a secret, so it seems to me that the first question disappears. And the position of Admin held by him is simply a coincidence (if I remember correctly, his candidacy was proposed in the chat, to which he replied something in the spirit of "why not"). As for the rest of the questions, some of us can easily give an affirmative answer, including me (especially those who were at least a little interested in the history of the forum).
So if I had the opportunity to get an answer to one question, I would ask about the details of thread №3, namely, whether these mysterious logs remained at his disposal, (in case someone wants to correct me, I want to say that I know that he registered after these events).
