I had an issue raised that a student did a google images search on Reece Bennett and on the second page, after removing safe search from moderate to off, they got some inappropriate images. Blocking the preferences page wont help because there is a dropdown box to turn safe search off. Is there a way to prevent users from changing the safe search options? Has anyone sovled this problem before?
Some proxy filters, especially aimed for schools, have filtering that will automatically enable safe search from Google. I believe the filter we used from Microsoft had this feature, and I'm fairly sure that the big vendors for proxies and filtering have that feature built in.
