If these "robbed" acts weren't popular enough to beat the novelty acts then it isn't looking good for any future career. no point in giving them false hope. the joke acts provide light relief from the drama of the show (sometimes even adding to it) and always provide a good talking point. Last year wouldn't have been as successful if it wasn't for Jedward (and indeed they're the most successful act from last year full stop) whilst this year wouldn't be as watched if it wasn't for wagner (people watching to see if he finally goes)
