I mean, what do you expect from an explicitly (m)arxist-(l)eninist instance. Their entire religion is "west bad, russia and china literally the best" and censoring any wrongthink. And yet there you are implying Russia is behind a bad thing. Of course they'd take action against you.
Imo fediverse projects really need to federate instance rules. Just include them in the instance actor (if they aren't already) like you'd do with a community, then use them if available.
