I'd suggest to move even beyond "engage/ignore".

This is HN. The focus should be "does this person provide interesting or thought provoking comments", not "relationships" or "engagement".

There are plenty of HN commenters whose opinions I absolutely dislike (I'm sure it's mutual ;), but I still read them - they are at least well reasoned or point out missing facts. I don't have to like them to learn from them.
