Sorry for the click-bait title, but it seemed somewhat accurate.

I'm working as a counselor at a summer math camp, and have been tasked with giving challenge problems for the campers outside of their classes (see this post at [MESE][1]) for more details. I am almost certain that at least one of the students would know to look at MSE for help on the question, and would not be shocked if one of them thought to make an account and ask MSE for help with the question. I intend to make the problems distinctive enough that if somebody were to ask about it, especially during the appropriate time, it'd probably be recognizable. The problems are meant to be puzzle-type questions, i.e. they do not require any particular background to solve, but just some elbow grease and critical thought; as such, I think it reasonable that they work among themselves to solve the problem instead of resorting to the Inbterwebz for help.

What I would like to do is inform the MSE community what problems I am assigning, and politely ask that they not answer these questions outright for the duration of the camp (three weeks). I figure I can't be the first person to try and do this, so there would either be a mechanism for it, or a rule against it (on or off the books). So which is it? Thanks in advance for your help.
