If you have an area that has extremely good eq/preps/buffs that is balanced by puzzles you WILL have people who share information. And the availability WILL be balanced by how many who knows the answer.

So even if there will be no asshole that spams lists on dios there will still be groups who share within themselves. And they will not be revealed easily.

So in reality the design encourages OOC sharing in small secret groups for the extreme advantage you get when several people trying to figure out quests/puzzles, it's a 1+1=3 thing. And on the other hand you DON'T want to share IC because if things become too well known they usually get moved, changed or nerfed. As history has shown.

Puzzles in cf fits best in the Loch Grynmear style where the rewards are not so extreme. Or you could just remove the eq/preps from Silent and make people explore it for explorations sake.
