A few of weeks ago, however, I started noticing something far more insidious. I moderate all comments to my blog. This is something I started years ago to keep the blog somewhat family friendly, and to avoid propagating malicious content. Recently I also completely disabled trackbacks to avoid boosting the search engine rankings for sites that steal my work. This means I see every comment that comes into my blog. The other day I noticed one that contained nothing more than a link to a fake Google site: google-images.google-us.info/index.html.
