Intellectual Property law does not always seem fair at first glance, but really if you're trading off the back of the popularity of another site your view of the matter will depend upon whether you are the infringer or the victim.

I am sure that if any of the posters in this thread created something unique and every man and his dog copied that unique idea then you'd probably be wanting to take action too.

However in this case the UDRP complaint was on the basis of a number of factors, it prevailed.
