Should moderators enforce NDAs for software vendors?
Due to the rise of online courses such as Coursera, the number of questions paired with these courses is on the rise as well. Some of them violate the honor code of said courses (usually, they contain source code or significant spoilers to the homework submission), but they don't violate SO rules directly (or do they?).
What is the etiquette for such questions? Should we delete them, or should we keep them alive?
