First, and most important are some anti-spam measures that have been put in place. Most of these you don't have to worry about - they will help moderators identify and eliminate spam. But there is one thing that regular users can do to help fight spam is to report it when you see it. If you see a spam post, please click the "Report this post button" to let us know:

Instead of creating a new post that says "please delete this spam" or just doing nothing, clicking this button will notify the moderators so that they can deal with it. This saves the moderators from having to dig around and look for spam on their own. But like I said, there are other features in place to hopefully reduce the spam to begin with.
