Some communities there are literally calling for the annihilation of Ukraine

edit: Since people are either willfully or otherwose are missing my point, this is a pro-russia, pro-fascist hate group, therefore we shouldn't give them the platform to spread their shit. this is not about me seeing their community or then causing issues accross other communities, it's about de-platforming fascists.
Even then I believe that their voice should be heard. But If they begin a call for Violence or repeated offenses against the Instances rules I would defederat them.
As it looks their on their way to do that tho.
I would rather wait until they actually do smth violating the rules, then act prematurely.
