After a while, sure. But the damage would have already been done. I have only Aquilegia as a personal experience, but that was pretty much a realm that was subverted by some fool who was a bit myopic about taking over Flowrestown. Pity he never realized that the only meaning to those pixels on the map came from recognition of other players. Still, when all was said and done, that was that. He managed to ruin the realm for pretty much everyone involved.
