At my daughter's (high) school the kids have to manage social media accounts as part of the curriculum. They're an arts school that puts on plays, musical performances, etc.
It is fully expected that the kids post tasteful videos promoting their work (e.g. a pianist kid would have to post a video of them playing and they'll be taught how to make sure the lighting/audio is right). They also have the kids create all the school's social media videos (only certain teachers have the power to actually post them though).
They are taught what's bad and good about social media and they experience it. All the teachers know everyone's (non-secret, haha) accounts and they get graded on them! There's all sorts of resources for the kids and they're all so damned professional it's easy to forget they're just kids.
Things like bullying, how to manage comments/inappropriate posts, and how to deal with trolls/unhelpful negative feedback is covered and it's fucking fantastic.
Every school should have social media management and online etiquette classes.
What I wish they spent more time on is how to protect your privacy... But I understand the conflict there: If they teach the kids how to keep things secret, well, parents might not appreciate that 🤷
They will do this but then what option will they have left when they make it even more bloated and slow—since they now have this "extra room", as it were?
