However, I can't help think that answers to these questions would be much more fun, and much harder to crack, if they were temporarily anonymous and it was unknown to the audience who the author of the answer was.
Many of these questions can be cracked by opening the users best answers and best questions and picking their top three languages they use. Typically, one of these will be the answer, drastically reducing the time it takes to crack these questions.
Would it be possible to have a "temporary anonymous" answer for these type of questions? Where users could answer these questions without their name visible at first, until either, the code is cracked, the time runs out, or admins make it publicly visible for any feasible reason?
