I myself would never finish anything but the Thursday (or now Wed.) night quests if it weren't for spoilers. I would have to look up nearly every question because I don't watch movies 10-100 times to know the answers, and 40 searches for a pin isn't worth the time, especially with time constraints putting you back a few questions. My 13 yr old MIGHT get it done in half the time on his own, looking up only half the answers if he's familiar with the movies, my girls can barely do it with me giving them every answer step by step. Of course they aren't looking on Dis unless I have the page ready for them, but imagine the time if I looked up every answer myself, took the time to write them down, and then still had to babysit to help the girls through one at a time.
That is my personal opinion, shared by many but not all, and that's fine. If you don't want to use spoilers then don't look here and let yourself be challenged. I rather spend the time getting credits to build the new ride and making sure each of my kids has what the special was that was offered.
On the other hand, Dis people making difficult (trivia) quests (not just go here, win this game type) have a right to ask their friends, we dis people, not to spoil it because the prizes are according to fastest finish. Not everyone will get a prize, and they aren't all even as with the host quests. Some purposely put good prizes for slower players, but not all, and you still have to finish the quest to win anything. If we are greedy and don't want fellow disers to win the same prize all of vmk is winning, so that the prize might be considered more rare, then there is an argument for not posting host spoilers. Completely different from guest room quests with limited and varying prizes. JMHO
