They do seem to be aware of slash, as a term (like in ffslash.fanfic.me, one of their new websites) and as a category of fic about m/m (it shows up as a category in Fanfic.me's drop-down menus). I'm not sure how much they want to court m/m slash fans, though. Elf's crackfic got bahleeted, so that kind of thing seems to be too much for Fanfic.me. Perhaps they want to keep Fanfic.me for younger fans and keep the really adult material elsewhere, in places like ffslash.fanfic.me? *conjecture*

Forgot to mention - what I meant by my original statement was, I'm wondering how they're going to explain content like slash to possible investors/advertisers. Hence why I'd like to hear them talk about it :) Their new TOS doesn't give me much hope that they'll protect their users' right to post content that may weird out advertisers.
