What you just suggested he do is called ban evasion. And in 99.99% of the cases it is not going to help you. If I saw someone do such a thing to evade that kind of ban on my network, well that little say 20min ban just turned into 1 week. It is MUCH smarter to either a.) email the network and ask them to remove it, orb.) wait until it is automatically removed,
rather than evade the ban.
