To clear some things up, Enderman farms have been banned. They have been banned since Sun's spawner was removed. Why? Because Spirecraft is a survival server. It's not Survival when you have the equivalent of Creative at all times. We have ways of knowing when Endermen farms are made, it's just a matter of time until we catch it. If you're caught making them, your spawner location will be locked down, your chests will be locked, and your inventory will be at risk of being wiped. Just don't do it, guys. There's other ways to get XP that, although might take a little longer, works just as well.
So again, Enderman farms are banned. They are and always will be. It's not open for dispute. If you're caught building one or participating in one, you can be at risk. If this becomes a problem, the End could be removed completely. We don't have to have it on the server. It's a privilege, not a requirement.
