I left a bunch of comments in that vein yesterday. The thing is, you can’t answer the question of “how to measure air quality” withiut some sort of product. By contrast, if someone asks “how do I manage my time?” the answer can be free. So if you use a naive filter you’ll be more suspicious of the one case but not the other. But the baseline probability of product mentions is way higher for domains that require products! You can see from my karma and general comment history though that I didn’t make an account to do this. I’ve had an account 8 years and am interested in air quality, to the puzzlement of my peers. If there were new accounts repeatedly dropping the same products, that would be suspicious. Did that happen?
