If that is suffering than every child will always suffer, because an very normal part of childhood is someone finding a reason to bully someone else. It's part of developing understanding of social structures and your place in them, some kids will inevitably decide they must be at the top of the pecking order in their little personal hierarchy. You physically cannot prevent children from making up ways to pick on each other, there's like a doctor Seuss book about this for heaven's sake.

This isn't saying "stop trying to prevent bullying" but rather "if you are afraid of your child being bullied because they aren't on social media, them being on social media will not stop them from being bullied" and social media makes bullying worse because now it follows them around instead of possibly stopping at 3pm
