Hello,
You have to choose if you will run an auction or will just look for a good offer for your Pokemon. If you choose to auction it, you have to respect and follow Auction Rules(Here). If you are just looking for offers, let your Pokemon here and reject/accept any offer you like, but do not use anything that will link the procedure to Auctions. Auction Rules are binding for all participants. In normal trades, you have to deal in Price and Location with someone in order to have a completed deal.
This is an official warning.
