I don't follow you - what's wrong with the title?

I think he's just pointing out that the blog post title is blatant blog spam.

E.g. "Did kqueue willfully violate international law?"

"Did President Obama kill a baby in 1991?"

Etc.

If it weren't for this "blog spam", how would HN know about it? Obama may or may not have killed a baby in 1991 but pictures of him appearing to kill a baby would certainly be newsworthy.

It is a bit weasel worded, but there is at least some evidence of falsified information that makes this far from a "when did you stop beating your wife?" situation.

There's a general rule, though, that if a headline is a question, the answer is no.

Sounds like a terrible rule that would often fail you. Treat any questions as a headline false until proven true seems better.
