Does that include voting/subscribing? Or only comments/posts?

Well when a community is small, there’s pretty much no moderation involved most of the time. I started a few subs on reddit, I never had much to do when the subscriber count was below the hundreds.

Once it gets sufficiently large, there will be people willing to mod.

I’m new to the whole fediverse thing, but - if you’ve got an interest in a specific, uh… Sub? Fed? Community? Why not create one yourself?
