Doubtful, there are a lot of tankies that have been here (lemmy.ml) a while that openly support Russia's actions and have done enough mental gymnastics to blame it on the US / EU / or even Ukraine

Welcome to Ukraine!
Ласкаво просимо в Україну!
They joined over a year ago and haven't posted anything since, so I think it's safe to say that they aren't actively moderating. I'd recommend [email protected] for Ukraine news and [email protected] for Russo-Ukrainian War-specific updates. Both of those communities look to be actively moderated.
Who do you report inactive mods to? In reddit, the sub would be shuttered unless they found a replacement.
TBH, I'm not really sure - I've been asking myself that same question as well. Might just be a situation in which you'd need to reach out to one of the instance admins listed on the main page's sidebar.
EDIT: I just noticed two of the admins for the instance that hosts this community (lemmy.ml) have Fidel Castro profile pics. Somehow I doubt they'll do anything about this sub, so it's probably best to just look elsewhere.
Because of mod inactivity here I have created a new magazine at https://kbin.social/m/Ukraine_UA, where I will be regularly posting and moderating. Feel free to join
