MySpace clearly expresses in their policy that you are sharing your information at risk.  All private information given to Facebook is not sold or shared with third party advertisers or marketers.
  18. 18. Steps to Safety  Keep personal information private  Use a nickname that doesn’t identify location, gender, age  Only add friends you know in real life  Alter pictures to remove identities  Share profile and photos only with friends  Ignore harassing or rude comments  Never post sexually provocative photos
  19. 19. More Steps  Never meet with someone you only know online  Don’t post information, photos, videos you may later regret  Use privacy settings to limit access  Online choices have offline consequences  Once posted it is online, somewhere, forever
