Kinda, i would just let the people fill in the top 15 without any hints. Just type 1 to 15 in the hint boxes and then the corresponding answer in the answer box.
I'm not quite sure what you mean by "no offense". All I am giving is constructive criticism, and trying to politely state how immoral and needy going around advertising your quizzes appears. The point is, no offense will be taken. Many others openly speak out against this, and it is to your benefit if you can learn how to understand someone's intentions and what criticism is, so that in instances like this, you would have changed to better your reputation. I don't blame you, as I was once like this, but I am not going to argue my point any longer. A little bit of help is what I try to go around giving. If you don't understand, that's completely fine.
