I found such a rule "You shall not operate more than one WarLight account in a way that gives you an advantage in a game, tournament or ladder." in here http://wiki.warlight.net/index.php/Rules
So it's a question if having multi-accounts on one team gives advantages or not? It should not make much difference if we or somebody else operate the account. If somebody just plays good, then he can have himself on the team instead of some random guy only. Does it break the rule or not then?
