Facebook's content guidelines have sparked confusion, to put it mildly -- a lot of people are unsure as to whether or not they have to use their legal names, or whether it's safe to post breastfeeding photos. At last, though, the social network is clearing the air a bit. It just posted new Community Standards that don't change the company's stance, but should remove some of the gray areas. For one, it's emphasizing that you only have to use your "authentic identity," not the name your government recognizes -- important if you identify with a non-traditional gender. Facebook also clarifies that you can mention hate speech for the sake of social commentary, and refines its views on harassment, nudity and what happens to your account when you die. A few sections are completely new, such as one explicitly forbidding revenge porn and other forms of sexual exploitation.
