As far as I am concerned this account should be considered compromised as there is no way to know for sure it was not transferred. I really wouldn't be surprised if this account is simply a sock used by another more well known member attempting to maintain their desired narrative without risking their main account.
Everyone who disagrees with you is my sockpuppet. Case closed. Now that you don't have to sherlock around looking for dirt you'll have so much more time to implement your "standards". Thank me later.
