The article is pretty specific. First of all, it talks about school kids who you can't really tell to "be rational about it". Secondly, if you turn off your phone but people still organize multimedia mass-harassment behind your back, "turning off your phone" doesn't change shit.
A third point is that "turn off your phone" is incredibly dismissive. A person shouldn't have to live without the Internet due to the actions of one, two, or twenty individuals.
But they don't have to be a part of Yik Yak, etc. If you walk into a bar and people insult you, don't go to that bar. You also ought not be demanding that the bar be shut down either. Go somewhere else.
