What? 4chan is linked to child pornography? This paragraph alone is casting serious doubts on the journalist’s objectivity and seriousness.
It doesn’t matter who encourages what. The mods obviously don’t like it, but somehow 4chan spent years attracting tons of people who love to post child porn.
That's not how most reasonable people would summarize it.
I mean, you've also got the gore pics, the incitements to racial and political violence, the fucked-up hentai, the homophobia, the raids on children's games, and the incessant insistence that everyone kill themselves.
But maybe people at your middle school were more mature than at mine, and never tried to gross each other out by tricking them into checking out this really cool site called goatse.
