Pervy minds want to know!

There's a show I saw only the pilot of, and now sporadically follow solely from reading reaction posts from one fan on my flist. And since her posts usually consist of squeeing about the canon het pairing, I don't really hear much about the plot developments. Except now they've just found out that some character I don't know used to bang her brother, and now this girl and her flist are like WHY IS INCEST EVERYWHERE NOW OMG ELEVENTYONE!!!11! So, my question is, are they reacting to us dirty slashers and our freaky Wincest specifically, or is incest the new black?
