Very sad to know.
I did noticed, doing my usual [META] analysis for the Italian board, that the Russian board had a few problems in terms of post and merits in the last months.
I guessed it has to do with the ongoing situation, and also thought the interaction between Russian speaking users, if I may, could become more difficult.

Sorry to hear the tone in the community caused you to leave.
I think it is a net loss for the forum.
