Questions about how creating communities works, on pawb and lemmy in general.

Not entirely sure if this is the right place to ask this, but I figured it was the closest fit.

I've been thinking about creating one or possibly a few communities, mostly due to missing some that were on Reddit. Before creating any, I wanted to be sure of a few things:

1. Do communities have to be created on the instance one logs in to (ie, does the fact my lemmy account is from pawb mean that communities I make have to be made here?) I kinda assume it would since going to another instance's page loads their site, which I obviously am not logged into, but given my second question I feel like I should ask if there's a way to make one elsewhere.
2. Given pawb is a furry instance, do communities made here have to be furry related, or could one make, say, a community for some specific game for example that isn't explicitly a furry game?
3. Would creating a fetish-related community for one that is popular with some furries be allowable, or should I go to a different instance for such things? I noticed one or two on pawb already but I was unsure if they got any special permission to be created or not.
