In the early day, information was not required. You will come across a lot of older quizzes with absolutely nothing at all, and others with a snip of opinion or a joke. These would not be accepted today, but the old ones are still there, and do surface in games.
That 'last seen' anomaly I cannot address. Quizzical has certainly not been writing anything for a long time, quite possibly since 2002.
