You are conflating different things. Anonymous or not, people can post hate on the Internet. That's a question of moderation.

Personally I think it would be easier to just ban anything that is political altogether. Bluesky for example is 90% politics. Just because something can be allowed in some spaces on the Internet that doesn't mean it should be allowed on every single space. No reason for the "funny short video" platform to become a news/opinion essay platform.
