I didn't read any of the actual conversation that was going on in this thread, but if someone were to state in chat they weren't participating to "wait" for someone, it may have been viewed by the GM as:

3.2 Disruption. You may not in any way disrupt or interfere with the Game experience of other players, including the disruption of Square Enix's computers and servers.
That goes over what I stated in my last post about using the chat function.
