Can I avoid adding "security" questions? So I just learned of these security questions, I canceled out of the prompt yesterday and I managed to download some apps.

Do I absolutely have to add these? If I don't add them is it just going to keep nagging me every time?
Should you want to continue to use Apple services such as the App Store and iTunes then the questions will need to be answered, this prompt will appear periodically until you do so for information this prompt is usually triggered by an OS upgrade or on occasion when Apple changes the terms and conditions in the App, iTunes or iBooks stores.
