Yeah! Let's all hate on the graphics staff for not choosing the hats you made without knowing their reasoning behind it!
/sarcasm
People are always going to be disappointed wjth these things, you shouldn't assume your graphics are going to be accepted
A lot of (what you think are) bad hats might get through simply because of the category they were submitted as. Tough and smart probably have less submissions, so poorer hats might make it through. Wheras cute and cool has more competition, better hats might not make the cut
