Keep in mind that suggested questions are entered into an approval process through the vote of the Community members. This allows the content of the game to be evaluated and accepted by other users.
Sometimes, with many users suggesting questions on a daily basis, questions pending approval can take longer than expected to be rated and approved.
This is why, if after a considerable period of time your question was not approved, we suggest that you contact our support team here to find out about the status of the question.
