Exploring has become a single player thing or perhaps something for small groups. The extreme enforcement of secrecy has made quests and area explore an ooc advantage that if you reveal it too widely it punishes you.

If my battle bard character found an entrance to silent and some archmages it would probably be perfectly in his roleplay(or even bad roleplay not to) to write a note to battle and explaining how to get to these new mage killing grounds and the perils that awaits. But of course one cannot do that because it would be punishied and/or silent would be closed again.

If my fortress mage decided to write a note to help his fellow mages with their protection by giving out a large list of wands, then again it would be punished.

This system will of course reward imm knowledge and small closed communities that share information without it becoming public knowledge. And also exploration knowledge does not reward you in a way that makes you a better explorer. It rewards you so you become a more powerful player killer.
