Problem with posting GSA ser- scrapped article

Hey guys can anyone pls explain me why I failed . I scrapped 1lakh urls with proxy scrapper using GSA ser article footprints. I then removed the duplicates and used GSA ser to identify the platforms. Finally I got 13k+ article urls to post. So I created a new project and tried to post to those sites and the result is 0 showing error for each url as no engine matches. Can anybody explain how to resolve this problem. Pls help me
