Well the way laws tend to work they scale to consequence.

Like think about speeding in a school zone. You get caught by a cop doing it it's a fine. Nobody is going to jail.

But say you speed and hit someone and cause injury. You probably face big fines or a few days in jail or community service.

But then imagine you are speeding in a school zone and you hit and kill a kid. That's not ruled a no fault accidental death as it would be if you weren't speeding. Because you broke the smaller law you get the upgrade to manslaughter because you were found criminally at fault.

Cyberbullying applies the same logic. As long as there were no criminal harms and measurable damages it's a little fine to remind you that that's not cool. But the more recordable damages the cyberbullying causes the more you are on the hook. If you are a person with millions of followers chances are you have a lot of potential destructive power and it is wiser to keep your facts straight and your nose clean when it comes to calls to action to harrass someone who has comparatively very little ability to defend themselves.
