I have no opinion about his person.
But a few months ago I got a week(!!!) ban for a single emoji in the chat. In other chats (sports, English, Finnish) this never happened. I have an opinion about why it was done and why the ban was so long. If my thoughts are correct - all moderators of the Russian chat should be replaced. I hope I'm wrong.
This case also had a positive effect on the current moderators, their actions became less repressive, they learned to warn with text and explain. At the same time, unfortunately, this confirms my theory...
