Once a member is flagged all of their posts and replies go to moderation first and only after the moderator's approval, the content will be visible to others. Moderators and admins can flag a member from their profile page or the moderation settings.
This feature is a valuable tool for site owners as it will give them more control over the content that is shared in their communities.
❗ Note: You cannot flag Admins and Moderators.
How Admins and Moderators Can Flag a Member
Login with your admin/moderator account
Then you can flag a member from 2 places:
Navigate to the member's profile page > click on the (...) > Flag member
Navigate to Administration > Settings > Moderation > Members watchlist > Search for and add the desired member > click on the "Update" button to save changes.
How to Unflag a Member
You can unflag a previously flagged member from their profile page, or by removing the user from the flagged members' section under the moderation settings.
