You're welcome. Also, there is no PM "back log". If you have him on your blacklist then he won't be able to send you messages and he will get a notification starting that he is unable to message you. Please do take the GM's advice and keep him on the BL and let them handle it. Even by coming here and posting this you are giving him what he wants: your attention and concern. The best way to deal with something like this is to report it and move on.
