One other thing, looking at their FAQs on their site:

Q: What type of blogs are you using? Are these free blogs such as blogspot? A: No, all blogs are wordpress blogs, hosted on domains we own.

So, since they OWN all the blogs that the links are posted on, if google were to discover the blogs they own, then they could pretty much devalue ALL the links pretty easily.

It would be easy for google to set up a fake user account, make a bunch of blog comment posts with a unique text string in them, find all the sites that are displaying that text string, and then devalue ALL links from those sites.

Just something to think about.

I am not saying don't do it, but I am saying investigate other options. If it is too easy, then there is a good chance that your competitors will be using the same system, and therefore the value might decline in terms of your ROI.
