Agreed. One of the first ways creators build their communities are a discord or telegram channel.
As they grow they promote (often unpaid) moderators to help prevent unwanted content and manage bad actors.
I’m not sure we have the protocol level support for moderations needed yet. I know private groups has mod events defined - however unsure it’s enough.
And likely these communities will centralise around a relay or even purpose build micro relay - and I think it can then filter and manage content better too.
