The platform’s new algorithm for probing “fake news” by adding context-specific information to videos seems to have glitched.

YouTube is suggesting viewers read about 9/11 during Notre Dame-related streams, for some reason

There are limits to what algorithms can do, especially in times of tragedy.

As flames engulfed Paris’s Notre-Dame Cathedral on Monday evening, several news outlets began live streaming the fire on YouTube. Underneath several of these videos was a small gray panel titled “September 11 attacks,” which contained a blurb from the Encyclopedia Britannica’s article about the September 11 terrorist attacks.

Why in the world is @YouTube putting information about 9/11 underneath the Notre Dame livestream from @FRANCE24?

(Especially since it seems like, at least right now, ongoing renovations are the most likely cause, no indication of terror)

Ironically, YouTube’s crackdown on fake news has lead to its own propagation of misinformation.
