How does moderation work?

Hello!

I'm part of the great reddit migration and I'm still trying to figure things out.

Something I've not seen much discussion about is how does moderation work in the fediverse?

Is it up to instance owners, or do communities have a moderation team like reddit?

How does that work across instances?

It's similar to reddit. There are mods for each community, then admins for the site.

Each instance has admins and communities on those instances have mods, but they can also make someone a mod or admin from another instance.

So if I understand correctly then, if a mod from here flags this comment as being in violation, and deletes it:

All other instances have to download that decision and delete the comment from their own servers? That seems like a looot of data transfer

The documentation will be better at explaining than I am. It's short and to the point https://join-lemmy.org/docs/en/users/04-moderation.html
