UK of scandinavia Threatens Alliance

Today a threat to alliance was found, UK of Scandanavia messaged alliance's heir saying he would give the heir 5M if he overthrow me. I find this as a threat to alliance, and for me. The thing he did is not acceptable and we cannot have this. I will speak to all the members of the alliance about this. He is NOT welcome in alliance, food asap, or wild base. If one guy can do this, what can others do? I contacted the alliance he is (it might about to be was) in, and they say, “Alright, we'll have a talk to him once his online. Just to clarify - this member has acted on his own and his actions where not sanctioned by the Alliance.” Corforty is thinking about suing UK of Scandanavia in-game. Corforty Is furious on this, and he wishes no one else would do this. 
This is corforty national.
