First of all, 452's advice is good. You need to create policies that reflects what's best for the wiki. If you don't have any or don't enforce it, nonsense like this runs out of control.

You stated there are many problems with message walls. One thing I do (primarily on my wall) is to close the thread once the discussion is over and/or after a few weeks with no relevant posts. This prevents reviving them with nonsense.

State to them were they should post to start with and why this is the best place to do so. Based on your original post, it seems you don't mind randomness anywhere but previous discussions. You can also remove comments from previous threads that are off-topic to the original post.

Bottom line, if the wiki doesn't develop a clear policy first and have Admins that will enforce it, not much can be done to save the wiki. You need to make clear what's allowed and what's not. After you do so and no one is following it, issue short blocks to those that ignore the policy that seeks to improve the wiki.

The first step can be difficult, but personally, I would rather have no editors than many that don't care about improving the wiki.
