Thats if someone has dial up. When someone is on Cable, the server decides when the IP will change, you have no control over getting a newly assigned IP from an ISP (on broadband) unless you talk to them directly and work something out, or REALLY know what the **** you are doing.
I'd have to say that IP bans arent used because they arent practical. They worked when everyone had dial up, but now if they were to ban your IP, you would just wait AT THE MOST a few hours until you were assigned a new one.
