If we’re thinking of the same thing (related to ‘coal’) thats looking like it’s a 4chan troll site.
I've been around on 4chan long enough to know that "troll" most often is equivalent to what the site really feels, or at least some of the people on there. The "troll" or "satire" label is only there to try to evoke plausible deniability - as in the case of "for legal purposes my call for violence against this person is a joke".
i.e. the sorts of people - in general - who browse the more unsavory parts of 4chan/8chan/etc are very fond of their dogwhistles.
If you live in a Christian conservative community, you leave pamphlets full of gay porn outside church. In a progressive community, you make racist websites about interracial dating.
They aren’t pro gay porn or pro racism, they’re pro getting a reaction out of people, that they find hilarious. We encourage them with our outrage.
And, obviously, a lot of those kids are older and still engaging the same juvenile behaviors.
Which teenagers and which edge of society, I'm fairly certain they're not all the same. Also your post is what every reader of 4chan says when the discussion comes up.
