While at Work, Neil Would Spend a Considerable Amount of Time

While at work, Neil would spend a considerable amount of time on the Internet. After multiple warnings, Neil was fired from his job as a result. To get back at his boss, Neil anonymously posted several untrue and offensive messages about his boss to an Internet discussion board frequently visited by his employer's customers and suppliers. Which of the following is true?

A) Because the Internet remains largely unregulated, neither Neil nor his internet service provider could be held liable for such discussion board postings.
B) Neil's internet service provider could be forced to disclose the source of the discussion board postings.
C) If Neil's former boss notifies Neil's internet service provider about the offensive messages, the internet service provider should not remove the messages, because free speech is the cornerstone of the Internet.
D) Neil's internet service provider, not Neil, is the one facing liability for defamation, because it is the one technically publishing the offensive material.
E) Because the messages were posted anonymously, Neil could not be held liable for such discussion board postings.
