DO NOT USE MOBILE / CGNAT DEVICES WHERE THE IP CHANGES CONSTANTLY!
At this time, it is unfortunately not possible to whitelist users when your IP changes constantly.
You may inadvertently get banned because a previous attack may have used the IP you are now on.
So I suggest people only use fixed IP address devices until I can think of a solution for this problem!

Well, the chip's now here. It'll be a simple 2 minute job to swap them over as it's now socketed and I've not screwed the top on the C64.
