A self-policing community could be achieved in this way, though the possibility exists that a litigious person could try to take a complaint to court. The positive side is that they're going to have to pay their attorney up-front, because an attorney looking at an apparently valid arbitration clause will not risk his own money walking into court when mandatory arbitration has been ignored .... And attorneys' fees are an effective bar to litigation for most complaintants. It's only certain types of well-heeled people that remain a problem.
An access problem exists, though: if the community's recources are available on the internet, people will be tempted to link to them in ways that ignore the sign-in sheet; so every page will have to look for a "I accepted the arbitration clause" cookie, and give non-cookie users the agreement first. Also, people tend to copy and paste text -- sometimes with attribution -- into emails, online bulletin boards, etc. People who do this will expose content which members think is not going to the courts to the world at large, which is not party to the membership agreement. One needs to think about what to do with reposts, and whether arbitration panels need some guidelines, such as a Membership Credo, to inform their judgment as to what to make of complaints.
Lawyer-free zone is "interesting" in concept, but what does one want to do that one is afraid of being sanctioned for in court? Or is not the sanction, but the fear of the expense of court? A more complete idea of what you want out of the "lawyer-free zone" is needed before it can be designed. Keep thinking on it.
