Coin selling means trading real life money for in game currency or items outside of the official channels. AP may ONLY be purchased through our Billing Site or redeemed via Fun Cards. Both buying and selling "gold" is against the Tems of Service and will result in all related accounts getting banned.
If another user wishes to purchase one of your items from you, they may only do so with provided in-game capabilities - such as gifting Coins or sending you items. They may not, for example, offer to PayPal you 5$. This is against our Terms of Service and we will ban all accounts suspected of such activity.
You CAN buy "cash shop items" from players in game using gold.
It is possible to exchange codes that are worth AP (or bonus AP on purchase) for items/services in our games. This is not something that is supported by Aeria Games, but it is something that we allow. This is allowed, because AP codes (or coupon codes) have no value other than in our system, and as such are not considered sales for real money. Any transaction that involves real money (or items/codes that are redeemable for real money) is strictly prohibited on our site, and in our games.
Fun/Extreme Cards, Epins, Coupon Codes, and Gift Codes all fall under this. These are all part of our system, and as such can be traded for something else in our system. However, any trades are made at your own risk, and as such we do not provide any support for these trades (except to remove scammers).
