Now that I've seen it I suppose I need to figure out what we should do in this case. The general principle is that we moderate less, not more, when YC is part of a story (https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu...).
In this case, I suppose we can satisfy that rule by taking [flagged] off the post and leaving the sensational title instead of editing it the way we normally would.
I'm fairly relaxed about this sort of thing (e.g. some stories about Gaza and such should definitely on HN), but "firebrand says firebrand-y thing" ... yeah, that doesn't really fit. It's neither especially interesting or especially notable and we could have a story about this every week; perhaps even multiple.
What would be on-topic would be a an in-depth profile about this person, or something like that.
