I think CryptopreneurBrainboss means that they are searching threads where they can submit their low-quality posts without any effort, there are several topics like "will BTC die?", "when will the bear market end?", "when should I buy BTC?", "is gambling risky?" or similar.
with that being clarified then another variable that was not addressed in this experiment would be the commentor who shit posts. the should should have been comments on theirs as well not only the author of the shitpost. with the parameters set with this addition as well as taking your rank into consideration as well i think the results may differ slightly. higher would probably achieve more replies from the author. and if commenting was also on the shit commentators boost to the replies. keep in mind peoples underlying urge to feel important, or liked... or hell the fact that ego drives most peoples actions
