How to find Do Follow blogs on ScrapeBox?

Hello, I'm just learning to use the ScrapeBox and I ask myself how to find blogs with Do Follow links on the comments.

Is it possible? how can I find it? thanks BHW.

P.D.: Why is the word Do Follow censured?

With the do follow checker addon

Go to a High PR page where you should manually post a comment (captcha or registering needed), generally people posting there have scraped a lot of links. Use the "link extractor addon" to extract external links only, save the list, load it and use the backlinks extractor (you need a good number of proxies), transfer that list to blog analyzer, keep good ones and check PR of those. Keep High PR blogs then if you need filter them with the "Do-Follow addon"
