Laments of downvote heuristics seems to be a rather unpopular comment type as well.

Laments of downvote heuristics seem to be about why the complainer's immediately preceding comments were downvoted.

How often are such complaint framed as laments that political allies were downvoted, much less neutrals or opponents?

If everyone writing a comment of content type X also always added spam links, I would downvote overconfident speculation about why people don't like content X and how that makes them bad people.
