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

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) https://t.co/A3HP36epxx pic.twitter.com/ZheCMC5pcG

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