There are variations when the person posting the question is lying. People are aware of ongoing contests. This is one reason I ask for a source of the problem. At least once, some kid posted a problem from a long list of proposed questions, one that was not chosen since the desired conclusion was wrong. There are ongoing programming contests.
 
About lying, once I pressed repeatedly when a guy claimed his friend gave him the question. I kept saying there was no friend. In the end, it turned out there was a friend, and this was a question from one of the university entrance exams they have in India and some other countries. So, there was a friend, but this was still illegitimate. Meanwhile, if there really is a friend who got the problem from some organized contest preparation, this does not imply that the person posting knows anything about the context of that contest prep.

Let's see, I prefer if the OP knows what the words mean.
