You can do all of this with SMS.

Kids know how to download or use free texting apps and sites, giving them access to potentially thousands of different numbers from which they can engage in harassment campaigns. In fact, it's an incredibly common tactic.

Similarly, someone from Minsk and Timbuktu can do the same thing, they have access to the same tools.

My point was not "oh, social media bullying is some kind of special case compared to other ways kids today bully their peers". My point was "modern bullying is different from historic bullying, and dismissing modern bullying as the same as historic bullying is intellectually lazy"
