I don't want to know who built this villager breeder on the creative server, but in the future you need to be more careful. I was building when I changed my render distance and my frame rate dropped to 0/1 for about an hour and a half while I was trying to kill the 1200+ villagers that were spawning in this system. I destroyed the machine.

If you want to test infinite systems on the creative server, I don't have a problem with it. Just make sure they are totally and completely disabled before leaving them.

Good call. And the same goes for the main server really. While you're free to farm them and all, if it gets to the point where it creates problem for the entire server, you will be asked to remove it or at least make it less effective.
