Earlier quoted context omitted.
As a Mastodon instance admin, you just made an argument for me to never have a clearly-defined and legally-binding policy. Thanks. The main thrust of my user agreement is "hi I am queer lady who is out of patience with people being jerks and wants a nice place to talk, if you piss me off you can go find a new instance or start your own". It's not much more formal than that, either.
Sounds more arbitrary and a lot worse than Twitter’s policy.
You want a more lawyer-like policy with tons of explicit rules for people to try and work around, then run it yourself.
You trust your admin to not screw you over the same way you trust, say, the people who run that chill coffeehouse you’re a regular at.
