> I'm not a big fan of banning things like this.

I think this is a pretty perfect use case for banning. The harms are mostly derived from the business model. If the social media companies were banned from operating them, and the bans were evaded by DIYers, Mastodon and the like, most of the problems disappear.

When there's still money in the black market alternative, banning doesn't work well (see: narcotics).
