I had thought of that as well as a sitemap.xml placement but part of the fee would bring non-automated verification. Like you could only pay with a real credit card (not virtual) but nothing sounded super great. A do follow is only as good as the others on the site.

I already have the code there to make people do follow. I was just going to make an automated program that saw people who generate traffic and put it into a queue to manually check.
