You were not the first that this happened to - they've even kicked out mods without any warning (and literally told people to kill themselves), nor will you be the last. At this point it seems to be a right of passage that people must go through, bc it is administered by the Lemmy sourcecode developers so very few instances seem to want to risk pissing them off.

Blocking especially Hexbear alone solved 90% of my issues with toxicity on the Fediverse, and blocking Lemmy.ml brings that up to like 99.9% - there are trolls elsewhere ofc, just like there are some people who might have been worth talking to on Lemmy.ml, but overall it acts like a spam filter that much improves my happiness here.:-)
