It is now a crime in New Zealand to send a person an e-mail containing "racist, sexist, critical of their religion, sexuality or disability." On a related note, e-mail traffic is down by 95% in New Zealand.
New Zealand has passed a law that criminalizes one of the least desirable facets of the internet: cyberbullying. The legislation effectively prohibits sending messages to people that are racist, sexist, critical of their religion, sexuality or disability. The rest for determining harm will be if these communications were designed to cause "serious emotional distress," and if a person is found guilty, could face up to two years in jail.
