Does this forum have something against the Earth's satellite

Does it?

No. It is just that the moon isn't really a moon . The Earth Moon system is a double planet system. Hence the name Antimoon.

Well, the above is one reason. Depending on the criterion/critera, the moon can be considered as either a partner in a double planet system or a moon.

It is a moon comprising of antimatter.

Antimoon is the Afrikaans word for Antimony.

Future colonization and the greening of the moon.

Terraforming.

^Although, what we're doing at the moment is Moonforming right here on Earth, LOL.
So I reckon Antimoon stands for green, anti-pollution, sustainable development; that sort of stuff. Dig?
