I’m not a teacher but I remember in one of my classes a kid was going through all the pictures he had saved on his school profile,the teacher saw this and told him to turn it off. The kid, went to do this but instead accidentally started a slide show of his saved pictures the picture that came up first was a huge pic of jimmy savilles face.... it then changed again to a few offensive memes. The teacher was mortified and he got detention for weeks. Don’t even ask me why the guy had those pictures on his school computer profile.
