Voici la close qui parle de ta sotre de vente:
Is it a scam to ask for lots of money for an item?
It is not considered a scam to ask for large amounts of money for an item, but it is not in the spirit of the game to over price an item.
It is not our intention to set limits on what players trade. It is a player´s responsibility to make sure that they are paying a good price for an item.
We would suggest doing research prior to future trades by using the Runescape.com Marketplace forum or talking to other players.
Remember, the second trade-window is there to keep you safe from scammers. If someone is not giving you enough time to check the items being traded then we would strongly advise you to find someone else to trade with. Do not hit the ´Accept´ button in the second stage of trading unless you are totally satisfied with the trade. You will not get in trouble for scamming if you choose to take your time and check that everything is as it should be.
Mais voici une autre parti du règlement sur l´item scaming:
Is it a scam to claim an item is rare when it isn´t?
Yes
