My son is in year 8, he has a handful of close friends as contacts in his phone. Has been adamant that he didn’t want adding to a Class WhatsApp group. He has been added by the child that bullies him and then a really unflattering photo has been added of him by this other child 10 times on the group. My son is mortified that most of the rest of the class has seen it. He has obviously exited the group and blocked. I screenshot it before doing so, this shows who was in the group, who added my son and who put the photos up multiple times. Should the school be approached about this or should I speak with the parents of the boy who did it?
