Just give up trying. Seriously. Because we will ALWAYS find ways to get around it, so you're wasting everybody's time by even attempting such things. At very least, games can be downloaded and put onto memory sticks and played directly from the computer - no internet required, no filters involved. Unless you want to disable all CD drives and USB ports on all the computers, this is the first sure fire way to screw you over. There are many other ways to dodge filters or even remove them completely, and you can guarantee that people will never stop trying.
