Hello, I work for a small school district, and our students have been able to use inappropriate words in their search terms to access adult contact on google images. We have made it so that they cannot change their preferences to disable the safe search. However, it only works to an extent. Google does offer a higher level of filtering, called Strict filtering. Is there a way that I can FORCE the strict filtering to be used for all of our students?? We tried duplicating cookies and such with no luck.
