When bots fight, who settles it?

There has been a tiny, yet fierce, war raging behind our technology: the bot brawls. For years, bots on Wikipedia have been staging fierce incursions against each other, undoing each other's work in a continuous cycle of competing raison d'êtres. These skirmishes went widely unnoticed by humans until a few months ago. Anyone can submit a bot on Wikipedia, and if approved it can go out and edit 40 million articles all on its own. If its tasks are in opposition to another bot's tasks, only their creators can call off the warring bots.
