Many sites swap traffic in exchange for paying for advertising within their sites. Case in point, if you visit my site, there is a direct link to this site, with this site's banner prominently displayed on the homepage. I do this because I believe that this is the best pool site on the internet, and I am extremely grateful to you (MIke) for posting my articles and providing a link to my site as well. OTOH, if somebody is just using the "discussion" forum to peddle their site or a product (without permission from the site admin), I see no reason why you should not remove the post. The CCb had a similar discussion a few years back about the Predator Pro Pool School ads, and around the same time period I had one of my posts removed because I posted information about my products and services(which were similar to the posts that Charlie Williams had done for his venture). Go figure. Remove the post/posts, or follow the link provided and talk directly the site admin about your stance on this issue.
