The specific text:
More than one team in the same world
One person (regardless of account used) cannot control more than one team in the same world within the same conference or within 1,000 miles or less of one another. Violation of this rule will lead to a forced relocation or removal from one of the teams.
If an owner finds himself in this situation due to accident, he should submit a support ticket and request to have himself transferred to a different school or removed from the world.
