>>2128738HnK threads tend to start when Raws for the next chapter are released, usually with someone posting them in the thread.
Thread quickly becomes saturated with reposts, memes, and 'I LOVE PHOS!!!" posts, to the point it dies within 2 days or less of creation. Then the PAS translation hits on mangadex, and this starts all over again, sometimes with new and interesting speculation, but again, memes, reposts, and ILUVPHOS, and thread dies in a short time.
Sometimes new threads are made and continue on, but usually they get spammed and bumped off.
BTW, this thread appears to have a fair amount of new content, which is great
