What are the rules for using .AI domains?
At the moment the usage must not violate the laws of Anguilla. In particular, fraud is against the law. For example, any domain that is trying to trick users into thinking they are at another website so they will enter their user name and password is committing fraud. The domain will be either removed or given to the people who own the domain that was being impersonated so they can put up a warning or any info they want.
