Read the first message that sir william sent. It doesn't seem like a warning to me. A warning would be something like "hey you did this and we don't like it please don't do it again" Instead he brings up things that happened a few weeks ago and proceeds in a threatening manner. Also no one forced Boston to leave Kashmir.
If we as an alliance wanted to poach from Kashmir we would've picked some bigger nations than boston. If we really wanted to poach from you guy's we probably would have messaged your entire alliance. However I'm sure both NSF and Kashmir and mature enough not to message all of the other alliances members trying to poach.
I think it's made perfectly clear in the pm's that him receiving a message was an caused by our method of recruiting that doesn't involve us looking at every nation. He was put on a list when he wasn't in a AA and sent a message later.
Also there shouldn't be anything in those to smear sirwilliam if he isn't doing anything wrong now should there?
