I can assure you that the "shitposters" very much care if someone replies to one of their posts. The reason they care is because if you reply to their posts, they can respond to what you said for another easy/quick post.
I can not really agree to this, simply put , a valid question from a non shitposter requires both time and effort to reply to, if i wanted to increase my post count asap i would ignore 1miau's question and stick to the regular ( very promising project sir, i hope price will increase because of the adoption) kind of b.s .
Your theory would make sense if there was a lack of topics to post in, which is not the case, so this IMO renders your theory invalid.
