This particular link is a perfect troll — the headline stabs at your WTF button, then the comment linked to has zero context clarifying the reasoning but tons of technical details that fuel the nerd rage — people were so trolled by the perceived linkrot and cache problems that they didn't even bite at the obvious SQL & ORM bait!

I don't think you can fix this with code, much less your usual tactic of adding heuristics to moderate/voteweight/ban.

Not to be HN-litist, but I think this post is drawing questionable comments in particular because it's linked in several places from Reddit, from which we are likely receiving a flood of users uninclined to self-moderate.

I hope that one of the approaches you try is recursive on who tends to vote for whom.
