Nicole Arbour
Arbour's "Dear Fat People" video didn't come off as satirical as she'd hoped. While she just wanted to encourage obese people to lose weight, it couldn't have been more tasteless if she tried. She was rightfully accused of fat-shaming afterwards.
Adam Saleh
In 2016, Saleh posted a prank video of himself getting kicked off of a plan for speaking Arabic. Of course, that wasn't true, and the airline received a lot of heat for appearing racist before it was revealed that the video was faked. Nobody was on the other end of the line, and he'd made a friend yell in Arabic across the plane in order to make a scene.
