Butch Hartman 

A once great cartoonist gone sour; known for creating Fairly Odd Parents, Danny Phantom, T.U.F.F. Puppy, and Bunsen is a Beast. However his Hollywood career tainted his mind as well as having access to the internet to share his bad takes.
Most notably he has been found to have overcharged on commissioned artwork (in which price does not match quality) in addition to being caught tracing other artists artwork and selling them. Basically the Facebook mom version of Simon Cowell.

That guy, Butch Hartman. I dunno...seems a little looney. Fairly Odd Parents was good though.

the man who single-handedly ruined nickelodeon with his crappy cartoons like the fairly oddparents and danny fantom.

butch hartman's cartoons all look the same, and on top of that, they suck.
