Well, unfortunately for Mark Zuckerberg, Facebook is under fire once again. And now Twitter is getting all the laughs over a Facebook hate speech update gone wrong.

2018 just hasn’t been Facebook’s year.

This time it is for a hate speech glitch. At about 11 a.m. ET on Tuesday, people started to notice a new question on Facebook. For every post on some people’s News Feeds, Facebook was asking whether it contained “hate speech.”

“This was an internal test we were working on to understand different types of speech, including speech we thought would not be hate,” a Facebook representative told Business Insider. “A bug caused it to launch publicly. It’s been disabled.”

How people on Twitter reacted to Facebook Hate Speech:

Clearly, Facebook is not a fan of pet adoption.

No hate speech worse than Japanese food thriving in Austin.

Irony? Or conspiracy?

“My little Christmas heart is so full.” Pretty much the biggest insult in the history of the world.

The glitch was resolved before noon, and the question no longer appeared.

Facebook has struggled with hate speech on its platform.

According to Business Insider, “CEO Mark Zuckerberg hopes to one day have artificial-intelligence algorithms handle much of Facebook’s content-moderation needs. AI needs data for training, so users identifying hate speech may be useful in developing those.”

Global X Social Media Index ETF (SOCL) with the largest exposure to Facebook at an 8.85% weighting is down 1.27% Tuesday.
