I agree with many of the people in this thread that Fred is annoying and unfunny. There's also NightmareRH, who sounds like an 11 year old trapped in a 23 year old's body, and Sparc Mac, which copies Chris Archie and only cares about money, not the viewers. Other than that I don't really think there are any specific channels I dislike, mainly just ones that I am not particularly fond of (pretty much neutral)
