You are right, these container communities were meant for single posts, not necessarily for community engagement with posts perhaps. We see your content shows muted, perhaps some rules should be changed around community? Waves container is published in Town Square community where other content is still accepted. See how this season goes and you can change your alliance in next season to be more active and engaging where more people join and build their town together, compete for leaderboard within Alliance or compete with other Alliances/Communities on overall leaderboard.
