You're going to get a flood of porn, pirated content, illegal-for-other-reasons content, and, of course, nazis who have been banned from all the other platforms.
Which will, of course, drive all the normies away. (Well, okay, all the pirated content might not, but then you'll also include 'all the media companies' and 'the government' as your list of enemies.)
And if you add federated moderation (Like Mastodon did), you're going to quickly understand why federated moderation is a labour-sucking, drama-ridden, centralized-censorship, tire pyre.[1] (Like Mastodon did.)
[1] Mastodon instance administrators blacklist instances that produce problem content and problem users.[2] (Child pornography, nazis, furries, etc.) These ban-lists are centralized, because nobody has time to investigate every single other instance in the network. I hope you trust the person running those centralized lists!
[2] Oh, and if a troll group does not like a particular person, they can follow him around, shitting on every instance that he posts in. How do instance operators deal with this sort of thing? By banning[3] the target of the trolls, because then they can stop wasting time playing whack-a-mole.
