I see no reason for your comment, specially when the guidelines are clear about these types of contributions.

From http://ycombinator.com/newsguidelines.html 4th paragraph from the bottom

  > Please don't submit comments complaining that a submission is 
  > inappropriate for the site. If you think something is spam or offtopic, 
  > flag it by going to its page and clicking on 
  > the "flag" link. (Not all users will see this; there is a karma threshold.) 
  > If you flag something, please don't also comment that you did.
