It all started with the "Ice Bucket" challenge and has come to an end with the "Bird Box" challenge.

YouTube, one of the biggest platforms on social media, has updated it user agreement rules of conduct to cut down on dangerous challenges.

The online video sharing company is cracking down on harmful or dangerous pranks.

Updated policies  will no longer allow challenges that present "an apparent risk of death" and ban content featuring children "participating in dangerous challenges that pose an imminent risk of injury or bodily harm."

The "Bird Box challenge" featured videos of people engaging in activities while blindfolded and the "Tide Pod challenge"  led to people who were sickened by eating Tide detergent pods on camera.

The company is will allow "challenges" that don't showcase violence or show activities where people can get hurt.
