It was probably supposed to be a "clever" joke, but just in case it wasn't, ATF refers to the site All The Fallen.

When I registered on ATF forums I asked in the introduction section which of my content was okay. They said guro was okay as long as I have a warning and hide pictures in spoilers. So I'm doing and didn't have problems with that so far. They said alterations were not okay though, but oh well. I've pretty much quit making them anyway since I can now just make renders with Koikatsu.
