I think you're referring to a dynamic IP. Static means constant and non-changing. The average private IP is a dynamic IP. Static IPs are usually only used for websites and businesses. Between dynamic IPs and proxies it can become quite troublesome for the management of a site to keep out less than favorable visitors, but there is another alternative.
I do not know how viable or obtainable it would be through Sythe's current setup, but perhaps the administration needs to look into MAC banning. This is a technique that, instead of banning the dynamic IP of the individual, which can be quite bothersome, the MAC address (Media Access Control) is banned. Unlike an IP address, which can be dynamic, your MAC address does not have natural ways of changing. It is a unique hardware id number, specific to the computer you are on. The MAC address is generally derived from ones Wireless Adapter or Network card. You are essentially banning the computer from accessing the site until another Network Adapter is purchased and installed in the computer.
There are ways around MAC bannings including simply changing what computer you are using or something as advanced as MAC spoofing, but the former has limits (the number of computers you have) and the latter can be quite difficult. Also, it is notable to add that most programs that allow you to spoof your MAC address have a cost appended to them and are not available as freeware.
