I guess I'm doing a good job of pruning my inputs, the vast majority of the imagery I see online is from human artists whose work looks largely the same as it did before all these slop machines got popular, so I don't have as finely tuned a slop detector as you must.
(Although really "I followed a link from HN" is depressingly correlated with "the images in it are slop".)
I concluded "this is definitely AI" when I looked closely at one panel and what initially looked like a halftone pattern on a person was actually weird mottling that looked like an unpleasant flesh disease.
