I've had my full name registered as both .com and .us domains with GoDaddy for about a year. Someone registered my last name as a .com and wants to sell it to me. I believe I have grounds for a complaint. What information can GoDaddy furnish me to help in the process?
Since you are likely not the only one with your last name you do not have exclusive rights to it, unless it is somehow trademarked and even then, I am not sure that would work since it's likely a last name that others could have.
