So easy to kill a domain
As the author of MailScanner, I am one of the people who provide a list of known bad phishing sites. More than once, merely the presence of a domain name on my list has been used as the evidence for the removal of a website and its domain name, and the registrant being barred from registering similar domain names in future.
I find that quite scary.
Fortunately, all the domains in my list have been manually checked by a human being, but I could, if I so wished, put a domain on the list, write a letter of complaint to a Registrar and have the domain pulled.
I shouldn't be able to do that quite so easily.
