I’d be angry if you told me 4chan had an “algorithm” too… It had a raw ass bump order and that’s it (does that reward rage bait? Kinda yeah but so does any activity metric). Algorithms design to guess what posts you want to see are the worst part of modern social media which refuses to just show you all of a user or group’s posts in order.
This sounds like subtitles for a DVD commentary track, which were probably supposed to be a separate subtitle track but weren’t for some reason (or your player defaulted to them alphabetically).
