I don't support server name copycats, but we can't spend our time "policing" the server list for this kind of issue, nor would we be able to accurately determine which server is "authentic" in cases that don't involve major servers, nor would we be able to create an accurate, simple method of registering servers without the risk of the real server being locked out of their own name.
If it's supposed to be easy for server owners and scripters to get started, this is not an issue that we can spend significant amounts of time trying to rectify.
