> 2.) What counts as a claim? Is 'the sky is blue' a claim, or is that common knowledge? We clearly wouldn't flag common knowledge because using the flag when it's not necessary deprecates the usefulness of the flag, but then who decides what counts as common knowledge, particularly across different cultures and countries?
As a further point, what if a blog says "not a single cloud was in the sky" and subsequent facts show there was in fact one cloud in the sky - does that count as fake news?

I wouldn't say it's "fake news", but it would be a claim that would be deleted, yes.
That's also a common fictional phrase. What if it's part of a blog post that's a combination of fiction and non-fiction. Or it's quoting somebody, and that person in the blog post is wrong, but since it's a direct quote, it would also be untrue to change it? Or if it was true that there were no clouds in the sky when it was written at 9 AM but there were clouds at 2 PM and you don't know when the blog post was written?
And how do you account for metaphors, common fictional phrases and uses, in-jokes, and claims that cannot be verified but a person still has the right to make? For example, I have a lot of Web memories that pre-date the Internet Archive and Wayback. I'm not pulling my claims from nowhere, but it's not my fault they're hard to back up either.
