It’s not a secret: Update moderation-log.md · NixOS/moderation@e9d67b7 · GitHub
Quoting myself here from elsewhere: “Posts that get flagged by Discourse community members with a sufficient trust level get automatically hidden at first, although the moderators eventually have the final say (there is a review queue). Please don’t make any bad faith assumptions.”
We are currently hiding all posts that are off-topic or inflammatory.
