I think it has to do with what we want to protect. Not our physical lives, not tangible properties and goods.
On the pure technical side, tools and methods and regulations are doing their best...
On the front of the social presense and dignity things are unclear... Who are those with the best "eye sight" to identify the pirates...? Who will stand out watching and taking action instead of just spending time around...? What links the members of the new social islands to care for each other in difficult moments for their society?

Well... most questions than tips and answers placed. I believe that those with firm principles, and experience in the new ways of the online world should by themselves undertake a role whithout expecting any reward.
