The Atlantic's Alexis Madrigal, who has estimated how long it would take to read every privacy policy you encounter highlights an interesting bit from the "Linking Policy" in the Terms of Use for the London 2012 website:

"a. Links to the Site. You may create your own link to the Site, provided that your link is in a text-only format. You may not use any link to the Site as a method of creating an unauthorised association between an organisation, business, goods or services and London 2012, and agree that no such link shall portray us or any other official London 2012 organisations (or our or their activities, products or services) in a false, misleading, derogatory or otherwise objectionable manner."
