Well quests are different from something like a host event, if that was the case it might be a different story. But gaining items from quests, then using them to build, etc. I can't see anything wrong with. If VMK said don't use mules, I wouldn't. Also, just b/c you know answers doesn't make you a scammer, because you still need to play quests. And most people don't remember 52 answers. Plus with this quest lasting throughout the month, most people wont make a profit of them if VMK is closing 21 days after the quest ends.
