doesnt matter if they do, the point is this provides a type of whitelisting for
major domains that are being abused eg phishing, and scales down so you can even
flag up fakes for minor domains

just another weapon in the arsenal and what i like is that its very low overhead 
unlike some techniques, and is also managed by the domain admin
