Is that the site where you review other sites and get yours reviewed by others, isn't it traffic exchange?
linkreferral.com is a very good site. I generated my first traffic to ebookdeal.blogspot.com from thare. One of the best traffic exchanges and you are getting free reviews +
If your using adsense when doing traffic exchanges then expect warnings and even a ban from Adsense. I don't like linking to other sites in my posts to much but I found this site that gives you a warning message Google send out to people using third parties to get quick traffic.
