I can definitely see where they're coming from with the password. Especially knowing what happened with fanfiction.net and all of the angry mail they were getting when people discovered their children reading risque stories.
Though I do believe that it is a parents job to make sure their children are viewing appropriate content. It also wasn't that long ago that I was a minor, and I had no more trouble back then accessing smutty stories and the such as I do now, though I do remember being frustrated when I wasn't successfull in finding any Lois and Clark nfic I could read! :p
