A lot of the reason why the "recent" topics were locked was because it had more then one suitable answer to the persons concern, question, etc.
It's not about GMs not wanting to hear from the players, it's not wanting a topic that has been answered and addressed more than once to keep going on page after page and end up COMPLETELY off topic of the OP.
Perfect example? This topic
, started off with something completely different, was answered, and then just snowballed into a discussion that was off topic which is why it was locked.
Also, you have those
people who constantly want to necro old topics that are open because they have a question in the same "general area" as said necro topic.
I dunno why you would jump to this conclusion when the reasons are pretty clear, logical, and even sometimes stated why it was locked. Just GMs trying to clean up the forums.
