As far as the faked page goes, an open reliable identification system could make impersonation more difficult. There needs to be responsibility on the provider to be able to investigate harassment cases, but as the cases grow in number, I could imagine the costs becoming prohibitive. Maybe we need the equivalent of smart spam prevention tools to help identify potential harassment pages before the person targeted even realizes they are being impersonated or attacked? It comes back to software understanding intent or meaning, a hard problem by today's standards. On the social media sites I frequent (twitter, facebook and friendfeed) there are tools in place to identify abusers of the system.
