So this is the new fact checking, after the outrage machine is in full swing?
I think everyone has seen how this works with alt-right social news blogging, and we've already seen this blogger feed the flames with false accusations retracted later.
I don't agree with the likes of Zuckerberg (though I think even he is backtracking) that fake news can be algorithmically detected precisely due to this example blog. There is no proof of work in fact checking, so outraged "left"/"right" bloggers is worse than no information.
If there's something to feed to the media do so, if there's something to feed to special prosecutors or the SEC even better.
