Once again I am hoping for a ban on _smart_phones. Not laptops. Not tablets (although those could get tricky I admit). Not dumb phones. Details will need to be worked out (like smart watches or future VR devices). Maybe a combination of:

- SIM - large enough screen or video playback capability - camera

Easier to democratise enforcement (report and fine) and you don’t need to rely on the very platforms you are trying to restrict.
