I came across yet another one today - a story with a header cautioning me that if I was a minor, or if I'm the kind of person offended by bdsm, I should no proceed. So what do these authors think sick little bunnies like me are scanning a site like this for?
Personally, I think the site's name says it all, but if there's any further confusion, the disclaimer on the font page is crystal clear. These inessential warnings are just a waste of space.
Careful consideration of a story's codes by the authors should be more than sufficient to ensure there are no nasty little surprises for the readers.
