Keep the proxy anonymous and open. This way, you keep access to SF officially locked down, but the proxy server is still going to be accessible to the rest of the world.
I know it won't happen, but it would be nice to see SF take the stand based on its principles as an open source community member.
I have played this game on the Wii and it is definitely not for kids. Some of the killings actually made me squirm uncomfortably. However, the worst killings have been blurred out (a "rage-like" red fills the screen and everything gets noisy). Overall, it is what the rating says it is: a game for Mature adults... not for kids.
