The thing is I joined in 2013, and unless things were substantially different before then, isomorphisms of "+1" comments were always heavily downvoted to maintain the HN level SNR. I wasn't aware they were ever welcome. Also, many people share a comment consisting of one of the annoyances they list but go on to explain and elaborate. That's much better and just because someone goes "causation != correlation" doesn't invalidate their post if they give good reasoning for how it's relevant.
