Watch YouTube Stars Read Mean Comments About Themselves For #MakeItHappy Campaign

Anyone who watches YouTube videos knows that the "comments" section can be a breeding ground for nastiness. For YouTube stars like Hannah Hart, it's a place she knows all too well.

"You can get 99 positive comments, but if you get that one negative comment, it really just sticks out like a sore thumb," she explained in her latest video.

In an effort to #MakeItHappy and have the Internet be a nicer place, Hannah teamed up with Coca-Cola and besties Jenna Marbles, Colleen Ballinger, Lilly Singh and Mamrie Hart. The first call to action? Having them read mean comments about themselves.

But don't worry -- Hannah had them read the nice ones, too.

"It's so refreshing when someone's like, 'You know what? I am subscribing -- this is why you're wonderful," said Lilly. "And it's not some generic comment... 'cause I feel like oftentimes we only say things when they're negative."

So keep calm, YouTube on and just remember: haters gonna hate, hate, hate.
