While reviewing posts, I've seen quite a few instances of a new user posting an answer to a question claiming that the question is from a current exam/competition. The new user also usually calls out the person who posted the question for cheating and requests/demands that no one answer the question (the latest instance of this, and the motivation for this post, is this user and their answers).
I usually recommend the user's claim be deleted because it "does not answer the question." Is there some other accepted protocol for handling these situations as a reviewer? I've found this meta post on the topic, but the post is old I don't know if there has been any official policy put in place since.
