Custom URLs are still under development and the program may change. In particular:
We reserve the right to reclaim custom URLs or remove them for any reason, and without notice.
Custom URLs are free for now, but we may start charging a fee for them. However, we will tell you before we start charging and give you the choice to stop participating first.
You must follow the Google Terms of Service, the Google+ User Content and Conduct Policy, and the Google+ Pages Additional Terms of Service. If you violate our policies or terms of service we may take a variety of actions, including suspending your access to Google+ and your use of custom URLs.
