From a survey of 500 folks who left Mastodon for Bluesky: about half of them mentioned content warnings, and most of those responses pointed to what they perceived as unreasonable expectations for content warnings. Several mentioned that they got scolded for insufficient content warnings by people who weren’t on their instance. Others said that their fear of unintentionally breaking content warning expectations or other unwritten rules of the Fediverse made them too anxious to post, or made posting feel like work.

In other words, the Fediverse has been taken over by Karens.
