Trouble with Scrapebox

Alright, so If i scrape a list of sites using some footprints i found here; approximately 22k sites. Scrapebox fast post goes through trying to post some spun comments and a test URL. Of the 22k I got 135 "successes" according to scrapebox. When i check the links, I get zero comments found. While it is entirely possible none of these sites were auto-approve; that is not the case. I picked a couple sites randomly to test posting myself, and the sites did infact auto-approve comments with no captcha that would prevent scrapebox from posting. What is the issue here?
