Remember, this legal part is the underpinning. Unfortunately, it might be necessary, for the health of the site, to exclude people who do these things without intention - sad but true. This documents says that we can. There will be a guidelines document to go with it, which will be a policy document laying out how we are liable to interpret it. And just like the law, the fact that you can be prosecuted doesn't mean that you will be or should be, it just means that there is the legal basis to do it if necessary. In addition, there will be a guidelines for facilitators (aka moderators) which aims to have even standards of application. This will be a public document - absolutely no reason fro it to be private, we're all in this together.
