I have to admit, I question the point of barring all chunkloaders, unless there's been abuse in the past. I mean, without them, there's no point in automation. If I want to auto-farm something, I have to stand there and wait for it. So where's the advantage? If I go mining, I have to fill up my pockets then go back and stand there while I wait for things. If I can't automate them, I end up standing there AFK, which keeps the full players worth of chunks loaded, instead of the single chunk I would get from a spot loader. Might as well play vanilla.
