I don't know, but one of the most consistent patterns I've seen with chud posters, the kind that have just about zero post history in a place they get chuddy in until they post their chuddery, is tons and tons of nfl/nba or team specific fansubs.
My hypothesis is "social engineers" and freelance chuds build up karma points by nodding along in sports subs then go to /r/antiwork or /r/fuckcars to do one off bootlicking posts. It's weird but otherwise I don't understand the pattern.
It’s hard to fight against every crime story that has someone say “these people are animals”. As you can’t outpost lies with researched truth.
At best you can troll them and ban them.
On sports articles, just rip on owners and how your taxes pay for the stadium.
