tl;dr for lemm.ee:
In short, somebody posted a pro-Elon-Musk-doing-a-nazi-salute Valentine's Day meme and the mods left it up so people started complaining in other communities and the admins realized "you know, we never see reports from our instance's most controversial community" because the mods were quick to act leaving everything up. So the original salute poster was banned and all the mods were dethroned as the admins are taking a wait-and-see approach on what to do with the community.
I haven't found a comment about what happened at .world yet but there are zero mods for their community too.
Power tripping mods getting their comeuppance!
Wintermute_oregon was the main mod. There was some other guy who hasn't posted in over a year I think and a bot account so that left all mod decisions to wmo. This mod constantly would get into fights and ban the other person for winning, he had no patience for democratic viewpoints at all claiming they're the woke mind virus, asking questions could get you banned and the next day he'd comment about how nobody wants a real discussion. He was sensitive and actively wielding power. A true snowflake.
It's ironic the choice that cost him his position is a choice to do nothing, except that it was a very active nothing. He could handle reports faster than instance admins could see them so none of the reports were even seen by anybody but him and nobody complained too loud because Lemmy is liberal enough to leave the community nearly untouched save for a half dozen or so accounts spamming pro-Trump, anti-democrat articles with By Lines saying they were written by Tyler Durden (the narrator's imaginary friend in Fight Club). If you weren't praising Trump, you wouldn't be welcome back.
This was a shit show but now the mod has been taken out of town on a rail.
