It doesn't accept answers that are clearly right but it does let you tell them that after they tell you it's wrong so they can look into it and add it to the database. Annoying but I get it. Building the list of answers. However, they have misspelled words as correct answers in the data base. Like telling me MICKEY mouse was wrong, it should be MICKY mouse or Jeff BEZOZ instead of BEZOS. If you spell something wrong, you have to watch an ad to fix it. But sometimes if you spell it right too.
