Hi,
No, Netsweeper should currently be enforcing Moderate Safe Search. DUring the initial implimentation of Netsweeper we had this set to Strict to ensure only safe videos were visible, however we found that the Strict/Moderate settings within YouTube are not as accurate as we had hoped so we had to reduce this.
This is set at a System level currently, which means unfortunately this is not possible to override using either the Categories, Shared Lists or Local Lists.
The videos which are not allowed to be viewed under Moderate, when viewed directly through YouTube, will not display. However if you have a direct URL to the video which you cant find, you will most likely see a black video with some writing saying something similar to 'You must be logged in with a Google Account to view this content'. This can then only be accessed with an appropriotely aged account at this time.
Regards,
Charlie.
