They can't, under DMCA, engage in their own hunt for copyright violators. If they did, under DMCA they suddenly become responsible for any violations they miss. Instead, under current law they have to respond to proper notices, not engage in their own search. That's what we want them to do - follow the law by shutting down sites after a DMCA notice, following the procedure required by that law. If you never send them a notice you'll never know when they've decided to be johnny-on-the-spot taking down those sites.
