It acutally only restricts MAC addresses that are not on the list. How to get on the list you say? Pay the money then it gets your MAC and adds it to the list as not restricted. There is a way or two of getting around it. Easiest is to sniff the network and get a MAC that is usable and spoof the MAC address. I will not go any further on this. If you want to hack or get free service you will have to figure out the rest on your own.
