3) There is nothing wrong with hinting you are willing to sell. I'm willing to sell my home for enough money and I still live here. If someone wants to pay me 130% or market (not even an insane amount) I'm out tomorrow. The fact that I would sell for over market doesn't indicate bad faith which is the other thing that needs to be proven.
Hold your horses. Hinting that you're willing to sell is probably the worst possible thing you can do if a trademark owner is trying to take your domain away from you. From ICANN's Uniform Domain Name Dispute Resolution Policy, the first example of a bad faith registration is: " circumstances indicating that you have registered or you have acquired the domain name primarily for the purpose of selling, renting, or otherwise transferring the domain name registration to the complainant who is the owner of the trademark or service mark or to a competitor of that complainant, for valuable consideration in excess of your documented out-of-pocket costs directly related to the domain name."
Never signal that you're willing to sell, even as a joke. The domain is your baby, and you want it forever. If they offer an amount you're willing to sell for, then take it. But never admit before then that a certain amount would get you to change your mind. When Nissan (the car company) tried to take nissan.com from Uzi Nissan (the computer store owner) who had registered the domain long before Datsun ever began using their Nissan trademark in the U.S., they asked him how much it would take for him to sell. He replied, "A million dollars. Why can't you understand I'm not going to sell." Basically he pulled a Dr. Evil. Back when the phrase "a million dollars" was first coined and the average person made a few dollars a week, it meant a ridiculously huge sum of money. But today it's not that much money.
Nissan's lawyers immediately took the first half of his statement, snipped out the context in the second half, and presented it to ICANN as evidence he was squatting the domain to extort money from the trademark owner. ICANN then decided to take the domain away from him and put it in escrow until the dispute was resolved (eventually in Uzi Nissan's favor years later, though he lost millions because he wasn't awarded legal fees). If he hadn't used that particular phrase, he might have been able to continue using the domain throughout the legal proceedings.
