Ability to Report Spam

Hi!

While looking through the most recent posts stream, I have run into a ton of marketing spam posts from Chinese market info to vaginal cream markets, often repeating itself under different users. Yet when I try and report it as spam I can't. All I can do is flag it as inappropriate, and even then I am told that it takes three flags to mark it. 

Is there an option to report something as spam? If so where is it? If no, is there a chance that the option could be imputed? Even though I am a new member I would still love to be able to help the staff and report these spam messages.
