Yesterday Google Inc. (NASDAQ:GOOG) announced a Pages feature for brands. However The Sociable noticed something interesting in the policy pages on the Google+ Pages terms of service.
Brands and businesses ?may not run contests, sweepstakes, offers, coupons or other such promotions? directly on their Google+ pages. Brands are required to link to contests on external websites on alternative social networks.
Google reserves the right to delete promotional content from Google+ Pages. If a Page is inactive for nine months, Google also reserves the right to delete them.
