ICANN’s Compliance team put the new WHOIS inaccuracy reporting system live earlier today. (Oddly enough Google alerts picked up on the new page!).
The new system should make reporting issues easier for all parties involved ie. reporters, ICANN and the affected registrars.
They’re also including generic information on how registrants may update their own domain information. The new form may be found here.
The old WHOIS error forms have been redirected to the new one.
