If you think a specific question is not suitable for the timed games, you should send a correction note on that question. This allows editors to remove it quickly if they think that is appropriate. A general complaint doesn't give much guidance about where to look, and the specific mechanism used by editors for removing questions from games requires that there be a correction note sent on it. From what you have posted, I could spend half an hour scouring the relevant subcategory to find the original quiz, play it and send the relevant correction note before going to the editing zone, finding the message and taking the appropriate action. Even if I could edit that category, this is far more time than I have to spare for this - there are a number of new quizzes whose authors would really like me to spend that time helping them get online, as well as a number of corrections to be dealt with.
