Teenagers are complicated creatures. Admittedly, this stuff seems impossibly extreme? Maybe I am indeed rather naive. I must have frequented much more harmless online communities. I never understood the appeal of SA or 4Chan. At the same time I can see how, as teenagers, people can get sucked into these communities, where edginess lures one in with some kind of false promise of 'freedom' from the rules of a society that appears to have rejected oneself. Even if that rejection may be self-imposed. At some point it's just a competition for who can say the most horrific things. I don't know how one would counteract this. The funny thing is, I also cringe at what I wrote online as a teenager, but I never took it to these extremes. However, recognising it (and 'hating' oneself for it) is a first step in fixing the problem, hopefully.
