Oh, you haven't heard of it? Go to "My Zone", click "Settings", and scroll down. You see the "Cancel Account" area? I'll talk about that a little.
Already a member has been told to do it and they got themselves perm'd. You might know this guy and the trickster who did it, but I won't be mentioning them. DO NOT TRY THIS OUT ON YOUR MAIN ACCOUNT. Hullbreach has already said he will not unban cancelled accounts, despite one has already been unbanned. The feature was added because many members keep saying I'M LEAVIN SDK FOREVER HURR DURR. So Hullbreach added a suicide option in your settings. Only use this if you truly want to leave SDK.
I have already found a glitch over this matter, and it's very scary, I will say so now.
