Anyone can go to ICANN's webform and submit a complaint about any website. There is no human intervention because ICANN felt that there were few abuses of the system back when no body knew about it. You registrar will automatically generate an email and send it to you. If you don't respond within a very short period of time you loose the domain. The time to switch to registrars who protect anonymnity is now.
