It did work for me and it still does.
right, i dont believe you even know what you are doing tbh.
no offense, but did you even check if your guid is different on the server now? you have a new unbanned key and after doing this you still can connect - following noob logic that proves to you that this method works. doesnt mean the method works if you didnt even "enable" this hack in the first place (because you might be too newbie to even get it to work). if you did indeed
then stay on the server for a short while and wait for the kick, it will surely come.
whatever, go ahead and believe you have some new guid (and not get kicked for it) and get global banned again and only then realize that it was indeed your real guid that was banned. just trying to save you from getting banned again, but i doubt you will listen.
