Cousin domains are a major problem for ISPs trying to protect their users from phishing and other fraud. Because so many companies use cousin domains in their legitimate mail, ISPs can not be strict with them. Instead, they have to expend time and energy to determine if this particular cousin domain is legitimate or not.

It’s time, energy and other resources that could be used better.
