I believe that someone who has not made a note in the accounts of relatives / friends about their connection and begins to tell "stories" only after the abuse is found should blame himself.
Even if the “story” is true (I’m talking about theory and not about this case), then the one who hid the connection between accounts (while performing actions that are regarded as abuse) should be red tagged. He took the risks, these are his problems and responsibility.
There are at least three reasonable reasons why people do not make neutral notes in the trust about a kinship or friendship between accounts:
1. This is not required by the rules of the forum, and many beginners, I think, simply do not know about the trust system, in addition to the rules of the forum.
2. Caring for privacy.
3. Fear of the ban hammer, which indiscriminately punishes not only the account that violated the rules, but also all accounts associated with it.
There is reason to believe that your account is not the first and not the only one. However, there are no notes on your alternative accounts in your profile. Perhaps because your other accounts are already banned and you yourself are evading the ban hammer. Maybe yes, maybe no, who knows? The probability of a positive response is much greater than zero, given that your forum career was very winding and you did not immediately find your calling as a whistle-blower of reputation abuse.
