Pacifists?

These people had a funny ROE:
you never hit them - they never hit you
you hit them once - their whole guild will prey on you for the rest of the reset until the Land that was lost was regained. Otherwise, 1 for 1.
Example:
Your attack was successful and you gained 16 acres, while destroying 33 acres of land.
Then the guild would attack you until they had gained 49 acres and destroyed how ever many it took.
