@atomicpoet The problem with for-profit social media is that moderation is an added expense. Even Reddit with its thousands of volunteer moderators has to have administrators step in when things get out of hand. They have too often been slow to remove racist and misogynistic subreddits.

Mastodon seems to work because any administrator can quickly choose to isolate misbehaving servers. And people will move to the moderation they are comfortable with.
