Did you take a look at the list they put together? The list with interests from year before compared to the present list? Fanfiction was not more popular than movies but it was definitely more popular than god or beer. In the present list, there isn't any interest that has anything to with sex in general.

And until LJ makes a statement? Good luck with that. If users don't force them comment on what's going on, everything is just peachy, according to them.
