No, it's illegal to publish fanfics for money without proper permissions. There are some fair-use guidelines (e.g. parodies like Barry Trotter) but they are extremely limited in the US. What Kindle Worlds does is gets permissions from the rights holder. Amazon publishes the fanfics and for each copy sold, pays royalties to both the rights holder and fanfic author.
