Currently we seem to get quite a lot of capture-the-flag questions. The idea of these capture the flag challenges is not to ask for a solution on the internet, it seems to me. Should we possibly downvote these questions? Should we close them? Or should we treat them like homework questions and only give hints?
If the answer is to close them (or downvote & close them) what should be the close reason? Should we create a new one for it?
