Fully agree. Hobbyist moderators currently do moderation at-will. They may have a day job, go on a holiday, and of course they sleep. Without having several moderators across time zones, everything you said might become an existential issue, especially on larger and open instances.
And to add insult to injury, better anti-harassment features are near impossible to implement because of the nature of federation. Other instances may run an older version, or simply chose to ignore your new rules.
If and when Mastodon grows to the size as becoming interesting for many mass scale harassment attacks, the only logical way out is to disable the federation part more and more. Which means you basically end up with tiny centralized bubbles. For which you could have simply created a subreddit or Discord, for free.
Those tiny centralized bubbles would be run by whoever runs the instances hosting them. With Reddit or Discord subs/instances, you're still at the whim of the people who own them.
