Steelman argument is it's better to know what liars, bigots, and other naughty people are up to than push them entirely underground. And someday future moderators may think you're naughty/lying/a quack/etc.

IMO we should not let private platforms become near monopolies, and certainly not without regulation, since they become a defacto public square. But if we're going to let them eat the world, then hopefully they'll at least use good judgment and measures like de-ranking or even banning folks who encourage others to do harm. Making bans temporary is a safety valve in case of bad moderation.
