If you're experiencing bad quality traffic from one of your publishers sub-sources, you can blacklist them. With "Traffic Blacklisting" you can set up the parameter you want to have blocked.
For example: If you would like to block a certain sub source, you can write affpubid in the parameter name and the actual sub id in Parameter Value. Common paramters for blacklisting include affpubid, affpubname, siteid, sitename.
