I just cleared my slack messages from all communities I'm a part of and noticed that the same message was posted in multiple communities. Most have just become a promotion channel for most members. I believe one way to stop it by having paid communities with a moderated intent. Which are the top 2-3 Slack communities that folks here have derived the maximum value from? (Free or Paid and apart from s11s) Would want to be part of those rather than the ones that are not adding much value.
