Cheating is the correct term. If you post a question on here (or anywhere else) asking for an answer, you are not doing any work yourself (apart from posting the question) and the answer is there for any lazy person to see. If you use Google to look for an answer, by entering relevant parts of a question, then you and only you will get the answer.
It is relevant when the deadline is - some of us want to test our grey matter against the quizsetter (and compete against like minded people). That is not possible with the cheats on here and the like who do no work themselves. Sadly, it is not only them that are culpable, but also the people who are only too willing to ruin a quiz and give the answers away. However, I do not see an answer to the problem - it just remains extremely frustrating!
