Gmail Report Spam feature

Does it really work? I am just wondering if the Report Spam feature of Gmail works, because I’ve been spammed by the same types of email everyday. What I mean is that, the spam emails I’ve been getting have the same content, just a different sender. I know we really couldn’t completely eliminate spam, but I’m just hoping that Gmail would develop or improve on their current spam filtering system to weed out spam effectively.

Well, until that time comes, I’ll just keep on reporting every spam email I get.
