In SALT Central, all users have the ability to mark content (discussions, documents, blogs) as abusive.
Users can also specify the type of abuse they see:
These reports will show up in the Admin Moderation Queue under "Actions" on the left side of the screen. To find this, simply click "Actions" in the upper right-hand corner of your screen. From the Moderation tab, space and community administrators can easily view the content, edit it, approve it, or reject it.
If the content receives 3 abuse reports by end users before an admin views it, the content will automatically not display.
