Hi Ross,
Grasping at straws here I think. A parent is asking us to block her student from viewing YouTube videos. Which we are already doing through Securly and Google Workspace settings. So my thought was that maybe he is viewing them on a non managed device. But thinking about it further, even if he was using a non-district managed device with his district email address, which is my only option for tracking purposes, both of those would still filter properly. So I am guessing that he is either using a non-district account AND a non-district device. Or possibly a sibling or some other unrestricted user account.
I feel like this falls into the category of trying to find a tech solution to solve a parenting issue.
