It is not "ringfenced" - it's just annoying and unnecessary to need to ask questions in this quiz.
Teams of people work hard to collect and collate answers only to have difficult answers broadcast to all and sundry.
Like a lot of other quizzes, it is being undermined by people jumping straight into Answerbank and other sites before exploring every avenue open to them.
Some questions would take longer to type into AB than it would take them to Google.
Please wait until nearer the closing date (in this case 18th March - 12 days away) and not spoil things for the rest of us in the meantime!
