I appreciate what you're saying and it may well always look like that but some of the threads I see deleted there are older. Some of them violated the old rules too but once something has been allowed to gain posts for a couple of months it seems crazy to delete it (especially since there are 5 years of posts in the main forum that predate any subforums at all). I don't have a solution for you other than just to lock or move old stuff but TBH it looks like any old thread that gets bumped in the main forum is subject to deletion.
