Do I have a right to blog anonymously?
Don't know. In the United States, the Supreme Court has repeatedly upheld the First Amendment right to speak anonymously. No similar concept exist under Singapore law. However, there is no law that requires a blogger to use his/her real name when blogging. Taking this a step further, there is also no law in Singapore that prohibits a blogger from using anonimity technologies or techniques when blogging.
