@coolboymew @rms Yeah, the issue after word would be that like rms pointed out is that they'll probably use a form of irl id to enforce that which isn't a solution.
The only long term positive solution would first to be to forbid phone usage at school, no phones are permitted inside the schools and jammers are put in place.

Then you need to have a pedagogic project so that parents have some knowledge on how to manage all of this.
