The problem is that some of the words labeled as misspelled are acceptable dictionary spellings. It is not very helpful to be told you have spelled a word incorrectly when it is actually correct! Worse, it is detrimental.

Comment to your game comment: Did you know that "unuseful' is not an accepted dictionary word? Since English is a "living" language, it may some day be acceptable. The same is true for misspelled words!
