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. See Solving for positive reals: $abcd=1$, $a+b+c+d=28$, $ac+bc+cd+da+ac+bd=82/3$
Let's see, I prefer if the OP knows what the words mean.
