So in TNB I had the idea for a new tag. Homework-question. These questions would be tagged by a higher rep user (or poster). They would be placed in a review queue and discreetly taken care of. You could even add a bot to comment stuff like "Please don't post homework questions" these questions would be removed faster.
Or the tag could just be added so users can edit and tag the questions to allow people to find and decide what to do with those questions.
This obviously does not require to be hard. Just adding the tag would work so users can find the questions about homework a lot faster.
