If that's true, that seems like the sort of thing that would lead to a ton of false positives getting flagged for removal. I'm sure big news events like the Wikileaks Vault7 release would generate lots of comments. Doing a quick search on HN, I see the top posts related to Vault7 have <15 points and no more than single digit comments.

I find this worrisome. Vault7 is the type of thing that I would expect to generate significant discussion here.
