I've seen around 3 occasions of that this week, altho I have never seen anything like it before.
if I remember correctly they were:
smack talking a mod (FlyingSquid) for saying not to report the same comment twice, when they were different comments, and the report was spam
someone comparing .world with .ml in politics (as in there was a comment saying "this post will be overrun with .ml people, and then a comment going "but you are from .world") (Maybe Im part of the problem? I have been called out for being a fascist because I questioned the "puching nazis" theme)
one more which I can't remember.
Anyways, what is all that about? Are people really starting to hate on 50% of the lemmy population because of their instance?
Thanks for asking this btw. Just found it with a quick search wondering the same thing after reading yet another comment section (this one about Trump, Musk and JD Vance) that turned into 50% whinging about .world mods/admin and horrible reddit users turning their lemmy into a shithole. The answers you got here were really helpful for me to understand a bit more about the context/history of these spaces.
