Facebook and its parent company Meta flopped once again in a test of how well they could detect obviously violent hate speech in advertisements submitted to the platform by the nonprofit groups Global Witness and Foxglove.

Meta did not respond to multiple messages for comment this week.

“We picked out the worst cases we could think of," said Rosie Sharpe, a campaigner at Global Witness. "The ones the ones that ought to be the easiest for Facebook to detect. They weren’t coded language....
