Facebook has been forced to apologize after it spent hours suggesting bizarre, disturbing, and upsetting searches to users on Thursday night.

Typing "video of" into the Facebook search bar yielded disturbing results...

Multiple users posted examples on Twitter, with the site proposing searches including “video of girl sucking dick under water”, “videos of sexuals” and “video of little girl giving oral”.

Others reported similar results in other languages.

In a statement, Facebook apologized and said it was investigating the issue:

“As soon as we became aware of these offensive predictions we removed them. Facebook search predictions are representative of what people may be searching for on Facebook and are not necessarily reflective of actual content on the platform.

We do not allow sexually explicit imagery, and we are committed to keeping such content off of our site.”

The Guardian reports that search engine autocompletions are a regular source of concern for Silicon Valley. Google has repeatedly faced criticism over the questions it proposes for users, with suggested searches over time including “are jews evil”, “are women evil” and “are muslims bad”.

As a reminder, less than two weeks ago, Facebook was busted asking users if they think it’s alright for adults to solicit “sexual pictures” from minors on its platform.
