@freemo I notice that many of the ads I've seen this week are posted by accounts with the bot flag set. Since it's already in the server rules that bots may not post to the public timeline, can the server be configured to automatically detect and report such posts and mute them pending your review?

If it's a spambot you can suspend the account, if a legitimate bot you can warn the owner to post unlisted, and if a real user you can let him know he needs to unset the bot flag on his account.
