The short answer is no, your sites will never be penalized for using automatic backlink builders. Automatic SEO tools are used by me and clients of mine for many years with great success, and no one of them got sites banned.
However, some not very intelligent webmasters still believe this myth. If you want to learn more why your sites will never be banned or penalized, you should understand how search engines work. Let's say that search engines don't like automatically built backlinks and penalize these sites. Then it would be the easiest way in the world to become a billionaire and get your sites ranked in top of the SERPS. Why? You could get automatic backlinks building tools and promote your competitor websites to get their domains removed from search engines. It would take only weeks to outrank thousands of big portals and knock the competition easily. However, it never happens. It just proves that myth is busted, and you will never experience any issues using automatic backlink builders.
