EDIT: not a duplicate of Policy on questions based on homework or tests (which I was clearly well aware of, having answered it myself), since that question was about "homework"-type questions, without really considering the issue of ongoing contests with real prizes.
This question consists of the following text (originally split across title and body, before my edit):
Which nation has a head of state who wrote unpublished novels earlier in life, including one set in pre-Columbian America, written — according to a person who had read it — with “terrible passages” involving human sacrifices but also “great mastery of language”?
On the face of it, this seems to be a perfectly on-topic author-identification question for our site. However, I discovered - thanks to a deleted answer - that it's part of the Financial Times 2017 Quiz of the Year:
Q.24 Which nation has a head of state who wrote unpublished novels earlier in life, including one set in pre-Columbian America, written — according to a person who had read it — with “terrible passages” involving human sacrifices but also “great mastery of language”?:
This is a currently ongoing competition with real prizes:
First prize for the FT Quiz of the Year 2017 is 52 bottles of Laurent-Perrier Cuvée Rosé, an elegant champagne to enliven any occasion. Ten runners-up will receive copies of Lunch with the FT: 52 Classic Interviews, edited by FT editor Lionel Barber. [...] Promotion opens December 22 2017 and closes 5pm GMT January 5 2018.
What policy should we take on on-topic questions which are part of ongoing competitions?
On the one hand, they're on-topic for our site, and it requires user surveillance to even notice that they're part of ongoing competitions; if we decide to ban them, some will surely slip through the net. On the other hand, by posting such questions, people are essentially trying to get our help with cheating. On the gripping hand, is that really our problem? We're not the Internet Police, and it's not our place to stop them from cheating in someone else's competition.
- close/delete such questions on sight (deletion is preferable to closing, IMO, since they're not off-topic, and if closed but not deleted, even a comment might reveal the answer);
- close/delete them and then reopen/undelete them once the competition is over;
- leave them alone and let the competition runners worry about their competition.
