Luckily, Bloggerparty has not had much trouble with people signing up for traffic exchanges. But we do have in place measures to help protect myself and Bloggerparty members from getting in trouble with AdSense because of illegal traffic sources.

Put simply, traffic and click exchanges are banned from referring to our site, meaning that if somebody does sign up the site or their blog on the site on one of these websites, when somebody using such a website surfs to our site, they get an Access Denied and cannot even view the website.

You needn't worry about it at all. Anytime a traffic exchange shows up in the logs, it's immediately put on the ban list. Some blog traffic sites, like Blog Explosion, I believe are deemed "okay" by Google and are not banned at this time.

Just thought I would clear that up!
