Lol, Our school has had that in affect for a while, I belive a year and half (ish) - it started when the school found out about a group 'we hate miss walker' and 3 people were excluded since then, many people have recieved warnings and expulsions from groups! Its invading our privacy, I mean f*** off, I have enough of you AT school I don't want the knowledge of going ome and having you browsing facebook >|
