We have a local "celebrity" in my city, he posts prank videos etc and has about 20,000 followers.
He's got an audition for BGT and posted a video of him singing asking for comments and stated he does not want negative comments.
People are posting comments saying how amazing he is and he's going to win, when in truth his singing is just average.
I always wondered why some people go to these auditions when they really just are not good enough and its because friends and family encourage their delusion.
