Slack is not intended as a community tool and many people point this out.

There are alternative commercial platforms like Discord that offer more moderation and community features.

There are other alternative open source, or self hosted chat platforms.

There are a bunch of things that are more like forums than chat apps, but something in between, like Circle.

We’re not going to move unless we really really have to. We have 10 years of history in Slack, and many of our members open Slack daily for work. Many communities die due to moving and not being the default place people go.
