I remember Heartless pointing out the inherent flaw in limiting interactions. There are 3 people:
Person A, with 2 accounts
Person B, with 2 accounts
Person C, with 2 accounts.

These accounts aren't allowed to interact. However, all the 1st accounts can interact together and all the second accounts can interact together. Say you then want to hit an alliance. All the first accounts can hit one planet, all the second accounts can hit the second planet. Double the coverage.
