Google has a web page creator called Googlepages where you can “Create your own web pages, quickly and easily.” Problem is the webpage is built with the URL subdomain being [google username].googlepages.com. Your Google username is your Google account ID and is also your gmail address. So spammers can simply go to http://www.google.com/search?q=site%3A%7E.googlepages.com and extract about 13,000 gmail accounts (as of today).
Thanks to DaveN at DigitalPoint for posting this.
Until Google fixes this, I wouldn’t suggest creating your new webpage at Googlepages.
