There are no cheats.

Well, mostly. It's possible to cheat by creating multiple accounts on a server, sticking them all in one alliance, and having them farm resources for your main - and that's a nice way to get banned, if and when the staff actually start enforcing it. It's also possible to cheat by running scripts or macros, but that, too, is also likely to result in banned camp, even if it might take six months for someone to notice or care.
