This is well known, and why forums that wanted to maintain their quality would consistently lock such threads going back at least 20+ years when I started using forums. Reddit, Facebook, et al, do the opposite. Its why they feel so bad to use over time - they are engineered to tap into this and to promote it. HN thrives because they very consciously do the opposite.

I'm sure many of us would take it much further, but I hope we can appreciate its not an easy task.
