Haha, my question really was just out of curiosity. Not any sort of inquiry into why the IP of the offender hadn't been banned after the first offense.
I have a feeling this answer won't satisfy you though. So I'll expand upon. It was a silly question (even for someone with my limited knowledge of tech). One that I hadn't thought out thoroughly before posting. Of course you can ban IPs. So I can see why you would interpret my question as a question that was actually asking something else.
