For sites with what they think is valuable intellectual property, there's an easy way to prevent deep linking - use some kind of password control. It could be a free password, or a paid subscription. Actually, it seems that many newspapers are adopting this model - free access to recent articles, and fee-based access to older ones. I don't like it, but it's their content.
