We have a place to move these threads. However, we don't move them all out at once because then you would have some forums which look completely empty. Which would then make the appearance to new users there is no one that posts here.

If you were to come here and see a forum with 20 threads in it. Would you post in there? I mean wouldn't it look so barren and empty to you that it would give you the idea no one posts here?
