Endermen are neat and all but for creative server they are a pain, can someone make a mod that removes them or stops their ability from picking up blocks?
Be sure to search for the plugins before requesting them. But here, I did the "hard" work for you ;P http://plugins.bukkit.org/#ti=enderman&ta=all&au=&subm=false&pno=0
I don't think any of those 'disable' them, just stop their actions. http://forums.bukkit.org/threads/fix-emob-v0-4-disable-mobs-you-dont-want-1185.36951/
Wouldn't that have the same effect in the end results? EssentialsProtect can stop specific mob spawning - however I wouldn't recommend adding the bulk of essentials just to take care of that single job.
