As shit as social media is, I do think the aspects of it that allow stories like yours to go viral nowadays and bring eyes to a situation beyond the local community can be helpful.

My niece's school also had an intense bullying situation, and several students posted on Tiktok about it. The videos went semi-viral, and the school got bombarded with phone calls and negative Google reviews (I didn't even know schools HAD Google reviews until then lol). The regional news station got wind of it this way, and came sniffing around. Suddenly administrators were VERY concerned and attentive to the situation, when they couldn't even be bothered half of the school year.

I actually think the victim's family were able to settle something legally because a lawyer offered their services reduced cost or pro-bono, again by learnings about the situation from social media.
