4chan is still a bit of a black box to me. I mean, I guess that's the point? I am pretty curious who these people are, mostly how old they are. I occasionally go rummage through it to see if it's still 4chan, and it always is. 4chan is one of the few places/things on the internet that makes me genuinely uncomfortable.
4chan mostly is an interesting place because of how extremely toxic everyone is to each other but how little their insults mean to you because everyone is anon. The problem is when they start targeting real individuals and posting their personal info. It goes from jokes to real harm very quickly.
But I'm not sure its really any worse than mainstream social media. Witch hunts start on all of the large platforms. WhatsApp and Facebook are responsible for countless literal witch hunts where the accused were killed or brutally beaten. 4chan seems tame in comparison.
That's a good perspective, and a light I hadn't considered it in. The discomfort I have with 4chan is pretty similar to my discomfort with twitter, facebook, et autres. I guess with 4chan there is perceivably less accountability in the event of the harmful situations similar to your description, but I have zero real basis for that belief.
