I think the one thing we can say confidently at this time is channels that rely exclusively on manual moderation by one person tend to have very stale main feeds. Not pointing any fingers but have seen it quite a bit now. If you don't have the bandwidth or the team to moderate, better to leave it to the algo.

Manual moderation alone can lead to stale feeds. Algorithmic help is needed!☺️
