How do they prevent people sending the problem to a friend or a paid advisor and, thus, letting someone else solve it for you? "The same happens with time-constrained problem-solving. That’s not how real life happens. People need time to think and reflect on the problems they face to build the right solution. Because of this, we do not artificially limit time for solving a challenge." sounds very critical in that regard. If you have lots of time, that makes it much easier to get outside advice.
