My husband and I admin and mod a discord server and for the most part we have it handled pretty well. We have established reasonable rules and a levelling system for access to some channels, and get lots of compliments from the users about the tone we set and how we moderate. Having said that, it's not at all easy, as you all know. One of the things that I struggle with the most are those occasional people who don't break any rules but just monopolize channels. Or worse, they go from channel to channel posting inane stuff in every one.

I've seen this behavior be a problem in a couple of ways:

1. Something about that person's personality rubs people the wrong way.

2. Other people just get really sick and tired of seeing that one person post every few minutes all day long.

And with both of those, the result is that a lot of good people just stop interacting, fade away and eventually leave the server. Our general population isn't aware of this happening, but as an approachable mod, I'm aware of it because people tell me in private DMs.

What is the solution to this? Is it reasonable to have a "don't monopolize the discussions/channels" rule? If it is, what's a reasonable definition of "monopolize"?
