Probably related to their admin's (Rimu's) false claims about dbzer0's admins using LLM for moderation. Though it's been months since that was a topic and got debunked. Rimu is pretty infamous on yepowertrippinbastards (which is banned on piefed.social) for his mudslinging and silencing of criticism.

For .ml specifically see below, as far as dbzer0 goes, some of the admins have allegedly taken a "friendlier" stance to the Tankies. I don't personally believe they're going full tankie like some on the Threadiverse believe, but sometimes they make questionable decisions in pursuit of that friendliness. For example allowing hardcore tankie users to be mod in comms that were literally formed to be free of tankie influence/ideology/propaganda like !leftymemes@lemmy.dbzer0.com where the top mod is a known Tankie and openly admitted to being one just recently

Admins of .ml promote and enforce authoritarianism here's a megathread on them

You'll get banned for showing support for Ukraine or going against Russian narratives or if you remind them of Putlers promise to not invade or just shit talking Putler in general

Or calling out propaganda sites - https://lemmy.world/post/32776038 | https://lemmy.world/post/33416433 | https://lemmy.world/post/34051329 | https://lemmy.world/post/35919522

Or so much more, I actually haven't updated the megathread in a few months, but there's more recent stuff on !meanwhileongrad@sh.itjust.works

I’d say that these days that group contains four instances and dbzer0 is a member.

Besides that you can look around and decide for yourself.

I meant all of them but if that's the one that came to your mind first that's telling.
