JGM: Yes, my idea needs KWWHunctions interaction, as in the title it is not specified that it is out of the possibilities.
Anyway, any usable idea would need the help of KWWHunction staff.

If we want to make a method with the less staff interaction, then the best way is to make the thread much more "web2", allow users to rate hosters.
For example:
1 host / 1 thread
5 star rating next to the hosters thread title
First post is the offer of the host, then first page of the forum is ordered by: most upvoted comments (from second it can be /time/ linear), although it would need a comment up/down voting system (votes older then 1 month can be deleted, so only the newest, freshest useful comments would be on the first page - thats quite like a timeline without staff)

Anyway: if you want to use the easiest way, which needs the less staff interaction, only voting plugins can help with a strict(er) restriction on who can vote. (user with x post registered since y time, etc)

So no, without interaction noting will change and the whole feedback thread should be deleted, if only those ideas are useful which do not need any staff interaction - as in that case the goal can be achieved in that minute.
