I'm not sure how anyone does not believe Google goes after blatant link/PR peddlers.

Go after them in what regard? Lower their visible page rank? Filter their rankings? I see tons of websites that sell links and had no measurable ranking drop. I also see websites that did have ranking drops. Can you afford to assume these drops are for selling links, are a Google bug, or are drops related to some other algo adjustment or issue at those websites?

Assuming something in SEO just because you see it in 10% of the cases is not wise.

It's easy to measure and weigh results when you use controlled data.

As Miamacs pointed out, we are not the sellers, we are buying links. In my case, links I have purchased are 'in content' of the websites who are selling these monthly links to me.

I might also add that the websites are exactly on topic, although I do not believe that this currently matters from a ranking standpoint.
