I don't have many LJ friends (and don't go on many communities - I just don't have time), and I guess probably, hmm, less than a third of those friends are ones from any fandoms. So my experience of fanfic writers, especially up to a couple of months ago, was mainly limited to total strangers writing stuff. So I didn't get the... I can't think of the word... but no discovering them as a person, no disclaimer about whether it's something they think is really wrong but acceptable in fiction or suchlike and nothing about their reasons for writing whatever. Just people posting all weird contextless stuff and other people posting about how hot that was. Which sort of seems to be more of a Wincest thing than the SPN pairing I'm interested in (Dean/Cas - or for that matter the other couple of fandoms I'd say I was involved in) so is something really I can ignore mostly (well not always but more) now having figured out LJ communities and that but, it *seriously* put me off the whole SPN fandom for several months (I only started watching SPN last year) when all I seemed to find was people with bizarre and sometimes completely sick kinks and fans of those same kinks (well that and Sam/Dean domestic fluff which I also hate, heh, though that's not creepy as such). It probably is different when you know the people more or at least have some idea about them rather than just seeing individual pieces of fiction, but I still don't really have that; the few fandom friends I have now don't seem to write any of the stuff that would really creep me out or if they do then I don't know that they do.
