Help with settings for Verified list please

I have in excess of 500k of verified sitelist_Blog Comment-General Blogs. With a lot of do-follows
I want to attempt to post a comment to all the do-follows, and I don’t care about keyword matching etc. I’m doing some parasite linking. When I try to set it up, it goes through the list eventually but only posts to about 100. I just don’t get it. In Scrapebox you can just import a list of good urls and an post to them. How do I do that with GSA ?
