ICANN have upgraded the system used for reporting inaccuracies in WHOIS.
According to the announcement:
The Whois Data Problem Report System (WDPRS) has a number of advantages over the previous system, which was first introduced in 2002. Among them are:
* More detailed information is captured from complainants to assist registrars in investigating Whois inaccuracies
* Duplicate reports regarding the same domain name are not accepted by the system
* Reports concerning domains already on hold are removed
* Greater capacity has been introduced to allow for bulk submissions of reports
* Processes have been put in place to assess registrar compliance with RAA Whois inaccuracy investigation requirements
