You can have every user-uploaded avatar image to be added to a moderation queue for approval or rejection.
This article provides the procedure for setting up user-uploaded avatar moderation.
With this setting enabled, a user uploading an avatar is notified that their avatar choice is pending approval. Once approved, the avatar becomes available for the user to designate it as their primary avatar. It does not become the user's primary avatar until the user manually selects it after moderator approval.
After a user uploads an avatar, the avatar moderation queue becomes available to the moderator through a link on the Avatar Settings page in the Admin Console. Please note that the avatar moderator will see the link only when there are images in the queue waiting to be moderated.
To enable user-uploaded avatar moderation:
- Navigate to Admin Console > People > Settings > Avatar Settings.
- Under User Uploaded Avatars, select the Moderate uploaded user avatars checkbox.
- Click Save Settings.
With the moderation enabled, all user uploaded avatars must pass review before becoming available to users. For more information, see Reviewing User-Uploaded Avatars.
