/shop sell !

[Temple Priest]

The shop was made so that players could buy items that were otherwise nearly impossible to obtain without a tremendous amount of effort, and to allow players to easily buy things that are very hard to attain normally. allowing players to sell their items to the shop would not only destroy the economy and make soul shards absolutely worthless, but be subject to severe abuse... Like cucumberr said, people only have to get a few platinum coins in order to get very wealthy. About the players selling their items, When a player sells an item, its usually unobtainable from the shop, or less expensive than the shop price, and the uncertainty of whether the item was hacked or not does not affect whether someone wants to buy an item. If someone truly wanted the item that a player is selling, they would buy it. Also, if you see someone trying to sell stacks of luminite, it can be either: A troll who is using [i/p or just spamming Alt+click and really only has one stack, or someone who has stacks and stacks of luminite in a chest, in which case, screenshot it and report it here on the forums.
Also, you say you have seen many many hackers, But so long as a moderator is online to ban them, the problem is gone, and if not, screenshot proof that they are hacking, and report it in the report section.
