Can I get sued for writing and selling an article about "Facebook Security"? I wrote a 1000 word article (rough draft) about how to protect your privacy on Facebook, and was thinking about selling it. Will I need approval from Facebook to sell content that is based on their name? OR is it safe to even write and publish an article speaking on Facebook's establishment? I know this may sound like a silly question, and you all may even laugh at me. However, I know that there are so many hidden laws and regulations now days.
