Sorry but i have no idea how this merrit works as far as i understand its a thank you? Whats with this merrit so special? I do not remember merriting anyone I posted all the screens of my accounts and i still have my email address it has 2fa so it was not compromised so i do not understand how the forum had been compromised?
I do not have the account as i cannot login as its now under a different email address! I have never had multiple accounts you can check all my gaming/social accounts all are the same under sale666.
What proof is needed more?

Doesn't it seem strange to you that you gave credit at the same time frame for a post that was written more than a 4-month ago? Together with you, merit was given by other accounts, for the same message and at the same time. And so we tend to think that you had alternative accounts.
Were you all attracted at that hour to this star post?
Moreover, the one to whom you gave the merit received 5 more merits, thereby instantly growing in rank.
I can believe that it was a long time ago. But it's hard for you to agree that it looks very strange.
At that time, your account apparently still belonged to you.
