WC suggestion
So my suggestion is ban any sort of ads to join alliances...a chat shouldn't be used for that anyway in my opinion. That's what forums are for. Users could access the forum to learn about, and join alliances. That would also get more users using the forums and involved in the haypi community.
Now, if someone is asking about joining an alliance in wc, of course people would be able to say "hey join my alliance _____" or anything thats part of a normal conversation.
That's my two cents tell me what you think.
