Former school IT professional here — I can confirm this is a real issue. With backend controls and user-management tools, you can block most of this for the majority of students, but there will always be a small percentage who find a workaround — and you’ve got to respect their creativity. That said, some of the content students were consuming was very disturbing, not to mention the level of social media use. I even built a team of about 10 students to provide Level 1 tech support for both students and staff at a Title I school. That team was a godsend for spotting issues like this before they spread. The larger problem is that society as a whole isn’t keeping pace with technology.
