As Tom pointed out, we've maybe gotten off track a bit. At this point, the behavior that has been reported is not in question, as in "Hey, that's awfully suspicious - I wonder if they're a clan". It has been confirmed by the Devs and is as described by Tom and Indirik. The only question we're really left with is "does what Tom and Indirik have outlined violate the clause of the Social Contract that Tom has cited?". That would be the fair play clause.
Personally, barring further evidence, I believe it does. The fact that this group of players appears to organize and coordinate on a large scale with minimal IG messaging suggests that they rely on other means to coordinate, which gives them various advantages. They also appear to stick together and support each other no matter the circumstances. They are thus able to form an impervious power bloc in any realm that they have elected to set up shop in; with total unity, they never have to worry about spies or betrayal, or whether everyone in the group will vote for the clan's chosen candidate.
It's almost like multi-accounting, and isn't fair to the rest of the player base for similar reasons. After all, if every account in the clan simply obeys whatever orders are given without question and is 100% loyal, what is the difference between them and if one player simply created an equal number of accounts that he used as his puppets? It suggests an overall focus on control and winning over the enjoyment of other players, whether they be realm mates or enemies.
Finally, the reaction of other players says a lot. Realms win and lose all the time, yet we only seem to get this reaction when it involves this specific group of players.
