That can be automated quite easily these days. Just make your bot/scraper scan for anything that blames something or otherwise fits narratives that can be used as a vehicle of your own promotion, and hit that.
P.S. Not necessarily implying that the grandparent resorted to that.
I absolutely adore it when stumbling occasionally upon great musicians who have laughable numbers of listens on various platforms, dunno if that's mere chance or the algorithm trying to balance things out, but that surely brings some hope for the pure art.
You wish. It is becoming harder every day to find genuine comments or technical insights at the top of HN sections instead of blind love/hate for trendy topics.
Even among the "genuine" comments most of them are just people spewing things because the monkey brain has determined that it likes it when the number in the top right goes up and has figured out what kind of things to spew to make it go up (dare I say encouraging this state of affairs is the reason some platforms choose to keep score in such a manner).
Does it really matter whether you're reading something written by an AI shill, a human shill or a human (or AI) who's repeating the shillery? You're being shilled at all the same.
