Yeah your friend is lucky that he wasn't CWB'd for his threats. This won't be considered for quite some time and he will probably have to serve majority of it. Also his forums isn't banned, and you can not post for your friend, he must use the external appeals if necessary.
I said to be patient, regardless you still injected cheats and claim to have only used fullbright, we can not accept this as a justifiable reason or confirm that's the only thing you used it for and you will not be unbanned.
