I don't see how Amazon could possibly handle this better. Having somebody read every book before it goes on sale definitely wouldn't scale. Perhaps they could offer to verify a book for a fee. Then again, the problem might not be widespread enough. I think I would set up my web sites in the same way: as soon as users would push the red alert button for some item on my site, I would withdraw it from public circulation and mark it for reviewing. On the upside, once it is manually reviewed, it could not be flagged again. How else would you do it?
