There is a difference of 450 questions between Questions Validator and Quiz Viewer for Quiz party. I don't know if any future question that loses the original username when an account is deleted could be automatically be given the name of admin as a value to ensure both are equal.

It appears that if someone posts on the forum, deletes their account later then their usernames stays. If someone doesn't post on the forum and they have their question/questions accepted their name will disappear once their account gets deleted/removed. If dormant accounts were removed tomorrow then the number of blanks could be nearly 2000 for the English language Quiz party.
