Let's say you own GardenHose.us. If you send an email to a company called U.S. Garden Hose (URL: usgardenhose.com), are you cybersquatting? Is it demonstrating "bad faith".
If your email is seeking money for the domain, or even asking them if they are interested in buying the domain, it is cybersquatting according to both the UDRP panels and the U.S. Federal courts.
