I agree with Ryan, you shouldn't use that or any other software that looks too good to be true but I won't agree with the "earn links, don't build them"... Not anymore.
I have done that for years and I am now fed up with it. Earned links come in ages and ages. You will end up frustrated if you wait for back-links to come naturally. Meanwhile, your competitors will have built hundreds of back-links and you'll be out of the competition.
If all the top ranking sites were EARNING LINKS and not BUILDING them, I would have agreed with Ryan but that's not the case. Open Site Explorer clearly shows that. Pick any keyword and most of the time, you'll see that top ranking sites have not really earned those back-links but built them.
When Google and other search engines get better and can tell which backlink has actually been earned and which one has been built, I can agree with Ryan. Today, they only TALK about it.
rant over...
