my registrar is requiring me to update my contact information and they say that if its not accurate (in other words if I am LYING) ICANN can cancel my domain. I really dont mind giving away my email address, but my PHYSICAL address is a different thing. Thats PRIVATE and sensitive information and I dont want that to be public. I am paying my registrar to conceal this data from whois pages but still, I would rather not give it away so in the past I always submitted made up data. Can ICANN ever know its not really your address?
