We need our little sticky back for subjects like these.
Anyway, what you are probably looking for is a proxy. IP spoofing used to mean you changed the source IP of a packet, mostly used with DoS'ing a server, so no one could trace it back to you. The downside being you don't get replies back from your packets..which has obvious downsides when you are gaming.
Why does it have to be that server anyway? What's so special about it?
Maybe If you stop using those aimbots and wallhacks....Your ass wouldn't get banned.....Deal with it and move onto another server....Also remove the bots!!!! Cheating is for People who doesn't know the true meaning about working......
