Reselling items bought at reduced prices (because of guild membership or friendly status) from guild bots, bots owned by guild members, bots owned by friendly/allied guilds, or from guildies/allies is forbidden. However, you may resale items made from ingredients bought from aforementioned sources at any price you'd like.
The bots concerned by this are all the Trade Bots with an IRON tag And all the bots that have a Blue or Green guild tag.
You are not allowed to abuse a merchant bot in any way, if you find a bug or if you see a bot with a very odd price (alot higher buy price then normal market range or alot lower sell price then normal market range) contact the owner of the bot or the guild the bot belongs to so they can take care of it or confirm the price of the item.
You are not allowed to attack a Guard bot in any way, if you enter a guild map with a guard bot in it while exploring leave it at once, If you want to enter it again you have to ask the guild the map belongs to for permission.
