Yeah all the insight in this article comes down to the sentence "The big tech does not mind having a few false positives." the next paragraph about people trying to please the algorithm is such drivel since companies rarely mention what their algorithms look for and people rarely go out of their way to please an algorithm (unless they have some level of insight into the algorithm and it affects their income, generally).
Anecdotally, I find myself thinking about what might make my accounts look like I'm up to something, and avoid it. Also anecdotally, I've seen others on HN talk about doing the same. People may not know what the algorithm is, but they can make some reasonable guesses at what it might take into account.
