Atricle Distribution Tool

I am looking for program/software that allows me to submit article with spinned coding to a network of sites for backlink. Anybody have any suggestions?

Bumping

The best of all.

Article marketing robot. Price is normally $97 but use search button to get $87 link.
Next best choice would be Article demon.

Why is article marketing robot better than article demon?

I understand that they submit to article directories. Is there guarantee that those articles are going to get approved?

I was looking for some sort of private network of wordpress blogs.

Thanks for info. I might try it out what you recommended.
