I find that I am unlikely to choose the “Misspelled” category when submitting names because it has a negative connotation.
I suspect it may be a turn-off to some clients, who may think “I don’t want a word that is spelled wrong,” but at the same time admire names like Google and Flickr. They may be discarding names that are labeled “misspelled” out of hand.
A phrase that means the same thing but without the negative connotation of being misspelled would be “Creative Spelling.”
Creative Spelling is also a bit more accurate than “misspelled” for those types of names.
