A good place to see this pre-2022 (the ai epoch) is articles on less known bands from the late 2000s when Wikipedia was becoming more popular. Quite a few of them turn out to be copy/paste promo text. I know this because I did webdev work for that industry, and when I look up those bands on wikipedia I will recognize the text as text that I personally had to paste into a bio page 20 years ago. Since the bands are well known, nobody reports it (I admit I'm too lazy)

The real tell on those tends to be weirdly time-specific claims that tend to be wildly outdated ("currently touring with XYZ")
