The solution to this is going to an Instance that works the way you prefer. Not creating extra rules for this one.

People will sort themselves into the kinds of places they prefer, as time goes on.

You do know that these instances communicate with each other, right? So even though you can create a community elsewhere people will look for a community, find it and the mod can essentially get a community under their control for free.

I for one am happy to just build up my small niche at c/daria.

Funnily enough i intuitively stayed away from squatted communities because of their lack of content.

I mean, yes, I understand what you are describing. But squatters have a mechanism for dealing with them that already exists.

This strikes me as more of a complaint specifically about power users, which I simply don’t see a good way to solve.
