Referring to my anecdote- how is that navigated when you have you have 100+ troll accounts with dozens handles though? User is left spending a significant portion of their time blocking accounts. On the board I mentioned there is the added issue of still being able to see blocked users get quoted by those who you don't block.

Also I understand Musk's position in spirit but, IME it isn't a sustainable or beneficial approach for society

Whatsapp is having the same bot issue, with large groups getting spam from bots.

The problem is even worse than in twitter. So now the group admin isforced to close groups by requiring group admin approval.

This is clearly the best type of moderation: localized and user-driven. It is not top down.
