Hopefully the API is not based on input from the likes of Politifact, Snopes, Daily Kos, Huffington Post, CNN, etc...

At the end of the day, an API is just code, written by biased humans, which is what Facebook's "fake news" controversy reminded us of after the recent U.S. presidential election.

Like Sarah's "Why Comments Still Matter" post in 2014 addressed, sites like CNN.com or Popular Science really just disabled comments because they were tired of being called out on their facts (one of the best blog post's I've seen on the topic, btw).

TL;DR: I doubt this API changes anything, unless it's just another filter against foul language, or is somehow configurable.
