Ok, if I didn't make it clear.
F) All threads (with the exception of the Requests board) must now have a tag, the tags are: [A]:Auction, [B]:Buying, [S]:Selling, [T]: Trading.
.....[A] : Auction : For auctioning off art/items.
.....[B] : Buying : For requesting art/items.
.....[S] : Selling : For selling art/items.
.....[T] : Trading : For swapping items
You are missing a tag on this thread.
A) Auctions must have an end date or time (I.E. 25/Dec or 24 hours after last valid bid), minimum bid raise and starting bid.
You are missing an end date.
E) End dates & minimum bids may not to be altered once a valid bid has been placed.
From this we can infer that you need to have a minimum bid.
F) The minimum raise for all auctions must be at least 10tc.
From this we can infer that you need to have a minimum raise.

And to wrap it up, you ignored my perfectly clear warning.
