By base defenses I mean some kind of automated mechanism that will cause harm to other players that is activated by proximity, or a trap that trespassers may be unaware of and that causes them to be trapped or harmed (or killed) in my claim? And another clarification regarding the "Refrain from overly high/low prices." If I systematically produce a block or item, and make them available to all players for free, does this violate the low price rule?
Ah! A fellow Canadian! Not many of us here. Anywhoo. I've always been under the impression that as long as the defences remain clearly on your claim they are legal, and I believe the economy is aloud to fluctuate due to the production of blocks. Can't help you too much, there.
Would think defenses would be allowed, due to the fact that it is a PvP server. Regarding the free blocks, I would make that dependent on what the block exactly is. -V
Anything that can be made with agricraft, or otherwise automated. So it could be stone, or it could be diamonds.
