Reddit reviews The Legal Side of Blogging: How Not to get Sued, Fired, Arrested, or Killed

Here's my two cents about being anonymous online:

• Be prepared to be unmasked at anytime
  
• Use a different email account for everything related to your site
  
• Use a webhost who will not use your information for your whois listing.
  
• Never post a real photo of yourself on anything related to your blog - even an altered photo
  
• If you want to be super anonymous, only do activities related to this blog via public wi-fi
  
• Don't break any laws via your blog because it could lead to you getting unmasked.
