sprinter53, I think like many others on here, that this subject was fully covered in the link by lilsecret.
The answers in those two great quizzes often require much research and not readily in one's memopry - and the compiler certainly knows that. So entrants should feel free to search wherever - i.e. websites, forums, libraries, archives, databases, ask others, etc.
Or are you suggesting that if one doesn't know the answer then don't bother with the quiz? If the number of entrants decreased there would be many losers. The compiler, the entrants but more importantly the charities which benefit from those quizzes.
In all walks of life, if one seeks an answer, then they ask. And AnswerBank is designed for just that. Asking!
If, as suggested, Bill Maclagan (the compiler) has made that request in his newsletters, then perhaps a direct request to the AnswerBank editor might be the next move.
It is also sad to see that Kakuro is inferring that people who seek help from AnswerBank are less honest than others.
