Kesha is a terrible judge.

She is one of the worst judges i have ever seen. It doesn't matter how bad the singers are she always gives them a vote up, and sometimes she just gives them because she likes the person or doesn't want to hurt their feeling.

When she does give them a vote down it's for some stupid reason like last episode it was because she wanted the other person to go through. She never even really judges she either takes what the other judges say and copies it or just doesn't even talk about their singing just random things.
