Do you know about or have ever seen NextGenLinks? It is a relatively new (or at least latest available) link building system which builds backlinks for your sites which is almost 95% automated. The best part of NextGenLinks I like is that it builds one way links for each page of your site and not just the home page.

This is a dead giveaway to the search engines and they will no doubt drop sites that only have incoming links to their home page simply because it’s just not natural. This leads to a very unnatural incoming link structure that will get you penalized by the big search engines. One of the biggest footprints of automated link building systems is that they only build links to your home page.
