Yes, according to post history and self-statements it's pretty sure that account has compromised. Either it has sold or hacked, but change hands. Left negative feedback and let's see what excuse he provide.
Alt connected and using the same ETH address.
Are they connected in some other way? I mean had they abused any campaign directly? I think neutral feedback for other accounts would appropriate unless they abuse any campaign.
In addition to the fact that he wrote to me in the PM, that I made his life difficult, he did not deny anything. And I don’t think it’s a big loss for him. Since, judging by past Ratimov investigations, this account belongs to a very large farm.

And if we talk about the accounts that YOSHIE discovered, then they all evade the ban. Thanks to YOSHIE for help.

I will submit a report to the moderators.
