I really don't like the "fact checks" being done by news sites these days - that's your responsibility as a reader, tech can't do it for you. Even more reputable sites like Snopes tend to draw absolutist conclusions about things which I find are certainly not absolute.
To make this statement is akin to saying that the opinion of experts is useless. This is exactly what has lead to the flood of conspiracy theories, malicious mis-statements, and general degradation of the media commons that has put us in our present state.
I do not have the infinite amount of time necessary to fact check the flood of bullshit in social media, much less deliberate BS in politically motivated media. I rely on curators and fact checkers, experts and analysts to winnow the very narrow set of confirmable facts and conclusions from the vast sewer that you would prefer.
