Someone has been going around stealing fanfiction and publishing it. So far, this particular 'author' has been going around the Glee fanfiction, taking femslash fics, and changing them to heterosexual ones. She's taken Dylan Hart's Should Have Asked for Directions and has plans to steal JJ's The Knife Thrower's Daughter and change it to the Knife Thrower's Son. Another person stole Frogsr2Cool's story, If Only You Could See What I See and self published it.
The article on the 'author' is here.
If any of you post your work online, keep an eye out for it showing up elsewhere.
