given the huge jump between when the last backup was taken, and now it's only reasonable that there are a lot of recent looking threads in the for sale section that are not current.
i'd say that a blanket wipe of all threads which were in there at the time of said backup wouldn't go astray and will help people in searching for new items, and items currently for sale.
Threads in the for sale section won't be removed only closed as there are archiving and reputation issues involved with most threads.
i guess yeah. didn't think of that.
most people fail to see the date on the thread. common problem/excuse of thread diggers!!
