In an earlier posting I deep-linked to several Radio Shack(tm) products. I then observed that RadioShack.com's Terms and Conditions for use of their website prohibits any linking to their website without their permission:
6. Linking to this Web Site. Creating or maintaining any link from another Web site to any page on this Web Site without our prior written permission is prohibited. Running or displaying this Web Site or any information or material displayed on this Web Site in frames or through similar means on another Web site without our prior written permission is prohibited. Any permitted links to this Web Site must comply will all applicable laws, rule and regulations.
Note to Radio Shack lawyers: NUTS!. There is nothing you can do to stop me from linking to your website. Nothing. There is no legal theory which permits you to stop me. On the contrary, there is likely to never be such a theory because of the nature of the web. Every request is accompanied by an indication of the link that prompted the request. You have complete control over how your website responds to a request issued from a user's browser in the context of a link that came from my website. What you choose to do with such a request is entirely your concern and none of mine.
