Kim Kardashian is urging YouTube to take down all videos of the Momo Challenge, which instructs kids to commit suicide.
They feature a creepy figure that tells kids to kill themselves, and to keep the video a secret from their parents.
Kardashian reshared messages from concerned parents warning about the challenge, and urging them to be aware and cautious of what their kids are watching.
YouTube says it has not seen any evidence of the Momo Challenge on its sight, and if it did, it would take it down immediately.
