Last year I discovered a hidden link on a client site pointing to a template site with a PageRank 9. Wow! How did they get that. After some digging around I found the reason. They sold templates with hidden links back to their site. It could be a stupid mistake from their developer, so I am not outing the company. One year later they still got a decent toolbar PageRank 9 and no Google penalty.
