I would agree with you if interdicting a player was not clearly stated as not allowed in the group policy.
see the policy here:

or here the initial announcemenmt, 6th of December 2014:

It is not that we just invented those rules recently and without including the members. And with now over 6000 players it is just not feasible to use anything else than a zero tolerance policy. The first post of this thread and the
http://elitepve.com site state clearly enough what the group is about and what kind of behaviour is expected from, and by, it's members. I don't think it is asking to much to inform yourself about the rules of a group before you join.
Especially when the information is so hard to miss.
