Agreed. That said, I don't believe in making it easier for that data to be harvested. If I had a Facebook account, I would delete and use the delete tools - it won't get rid of information, but it will make things at least a little harder for scrapers to get. It won't have any effect on previously harvested data, but I always believe in making it harder for scrapers to get new data, even if I'm not able to make it impossible for them.
