Selena Gomez criticized on Facebook on Tuesday for allowing “lies about COVID and vaccines to be spread on their platforms.”

Axar.az reports citing foreign media that the singer had been responding to a tweet from the Center for Countering Digital Hate, a London-based nonprofit with the goal of “disrupting identity-based hate and dangerous misinformation in digital spaces.”

Their tweet featured an interview with CEO Imran Ahmed talking to the BBC about how social media platforms are handling misinformation. Gomez quote-tweeted that interview with the note that “scientific disinformation has and will cost lives.”

“Facebook is going to be responsible for thousands of deaths if they don’t take action now!” she wrote.
