There are plug-ins, settings, and "thread rules" that can be set in place with vBulletin.
If it were set up like the other forums that I frequent, which have ZERO problems, it would be like this:
- DVD's, Apparel, Misc.
- Cuemakers (Tools, Building Materials, Etc..)
In each subforum, you can only create one thread every 12 hours and can only bump once every 48 hours. It's not a written or spoken rule, it's a systematic rule that absolutely will not allow you to post unless 48 hours has past. The way it works is the thread is limited to the OP posting only. You want to know more info? Use private messages.
I still think this discourages honest asking and answering of questions. I would only modify this to make it so these boards sort by thread start date, and not last post date. That will completely stop bumped threads from moving to the top.
Edit: You can try this yourself right now: just go to the bottom of the W/FS page, and select sort by thread start date. Now you don't see any bumps screwing things up.
