From http://googlegeodevelopers.blogspot.com/2010/03/introducing-new-google-geocoding-web.html:
(with geocode replaced with masturbate)
2,500 requests may be sent to the masturbating Web Service per day from a single IP address. This is independent of any masturbating activity generated by applications using one of the client Maps APIs for masturbating. Maps API Premier quotas remain unchanged.
