If there was one or ten bad comments on this thread - no problem. What if there were ten thousand bad comments?
I'm concerned that too-well-written posts will be thrown out-- a race to the bottom in legibility and grammar just to make posts more human-like, even if written by bots.
The thread collapse "[–]" already exists.
HN karma is pretty worthless outside of enabling a few capabilities here, and it's rather easy to attain those thresholds with some thoughtful participation.
What would be the point of flooding HN with tens of thousands of bot comments?
Malice.
