I can prod at a model as much as I want to produce something I find more original than average, but there are plenty of people out there that will say it doesn't count because of the fact an AI made it. "Slop" doesn't just mean "it sucks because it's bad", it often means "it's sucks because it's AI". They'd argue that if you were creative enough to produce something so original you wouldn't rely on an AI to make it for you. It's tainted by association, all the way back to the multi-billion-dollar enterprises that originally trained the models for their own ends.

Also there have been dozens of HN submissions and comments where the poster didn't even bother to remove the em dashes. Most people just don't care. The people who continue to post like this wouldn't have been as visible had they not discovered AI and pounced on it, but they were always there. The idea of posting with an AI voice, em-dashes and all, would likely have still appealed to them if you'd asked 5-10 years ago. Nowadays it takes hardly any energy for them to have a persistent voice.
