there's a lot of hetfic in the f/f tag for dragon age fics at least and a lot of them don't even have a f/f ship tagged in the first place and no it's not some f/f AU version of a het ship either

i think they do it to get in as many tags as possible but it's annoying to me because i have to scroll past so much fic in search of some femslash to read because a lot of it's just het
