Here's a story that illustrates how the rapidly changing face of the internet has ramifications for the law: UK celebrity Jordan made headlines when she claimed that she had been raped by a famous celebrity. Numerous Twitter uses posted tweets naming who they thought the guy was.
These have been deemed defamatory, and the celeb named could win substantial damages. However, it might not be worth it in the end because of the speed with which new tweets are posted.
Another story that involved legal issues and social media occurred earlier this year after the Victorian bushfires. Facebook users posted photos of the main suspect, leaving them up in defiance of a court order.
