The crazy part is that just looking at how people behave on Reddit and HN, I could easily see adults with the same outcome as Lord of the Flies.

It also could be that children are mostly posting, however (since there is no age verification, it's hard to tell these days).

I think you're misconstruing the point of Lord of the Flies. It is not a children's book, and most of it's commentary can be generalized to adults. We see the exact same outcome in the highest echelons of politics, business and academia alike.
