Where it is common knowledge to most who trade here, few sometimes make the mistake of starting a misc thread then posting there item in FS/FT after receiving a valuation, there seems to be no clear cut rule in the FS/FT rules as current, I think it was there before the change, I also think it lies under this quote:
"You cannot list items if you have a live listing for the same item or item type elsewhere.
This includes ‘Wanted’ threads. This is aimed to ensure that all negotiations are contained within the thread and no reference/bargaining to offers made elsewhere. Members do not always have access to other forums and are unable to verify such statements."
This does not state misc valuation threads.
Though it would be better if it did state valuation threads on this website as it clearly could be used as a way of gathering attention to an item without using the bump system.
FS/FT is in need of sticky help section to highlight issues such as this.
