eastendboy mendalshtam only closed that account and started another one. He had inadvertently used an engine in a few games only, thinking it was allowed as is the case on may sites.
Indeed I mentioned earlier he was in that very strong tournament group cuendillar won and showed us in an earlier post.
Note that mendalshtam/achmatova has a FIDE rating of over 2200, so he clearly has a lot of ability.

Hehe, exactly what I thought: people LOVE to play advanced chess against humans. After all, if you want tough advanced chess, you go to ICCF.
