Currently what seems to be working bullet proof is suing individual infringers (when done right of course), because in that case infringment is clear and well covered by current laws. And with SOPA coming more responsibility will shift towards sites' operators rather than "blame it all on user" which seems to be dominant approach nowadays. So this catching up you're talking about is taking place, but of course it's happening too darn slow.
