That's not
at all what I'm saying.
This specific case involves a specific group of people. I'd be equally annoyed if people on the other side of the spectrum used what amounts to a bug in HN to influence search ranking for a smear campaign.
HN makes flagged posts and subthreads invisible to its average users (you need to link to the subthread), but keeps them fully searchable. And does not moderate them. As a result, it's an easy way to deposit unreviewed content on a high-reputation website, leeching of that reputation.
It's got nothing to do with politics, and everything with the fact that when you allow a community to be publicly associated with content without letting the community see or moderate the content, you're damaging the community's reputation.
HN should fix the bug. That's all. Everybody involved in this particular drama is entirely entitled to say whatever the heck they want, just not under the cover of being pretend-part of this community.
