I would say that if there is an accuser, then he must prove guilt, not the accused.
I agree.
I've been looking at Gigabit's post history. In my opinion, it differs from the moment that, in the past, a person was an experienced miner and wrote quite lively posts; after a while, we see only general, dry posts about mining. I can say by myself: I am not a miner, and I don’t know all the subtleties, but I can successfully read any article and retell it in my own words. This happens in Gigabit posts after a break.
We communicate on the forum, and quite often people who have experience in this or that activity write on their own behalf. Gigabit never said he was a miner and knew all his secrets, although you can see completely different posts earlier.
But it is not worth relying on these cases to determine whether there was a hack or a change of account. Similarly, people are not required to keep their old wallets. Indeed, a lot of time has passed.
The bottom line is that even if Gigabit isn't the actual owner, it's pretty well disguised. I think there are a lot of such accounts on the forum; it's just that people don't treat them correctly.
Regardless of whether the Gigabit account was hacked or not, thankfully what has happened here (by bringing the Gigabit account in to the spotlight) is that we can all look at it conclude one way or another if the original owner/creator is still operating it. All that is missing is a little more input from the accuser (loginsam45) which might back up his claim to connecting the remaining accounts.
I had previously replied to a post and I am repeating that I clearly deny the allegations against me. The user 'loginsam45' has falsely claimed. He has been asked to prove his allegations but he has not done. Furthermore, I have directly refuted their claim, so it's only fair for him to provide substantiation. On the one hand he is a newbie and on the other hand his baseless claims. So, it will depend on you how you perceive the matter and how you will approach it.
