I joined hubpages recently and created a hub. When I published it, I found all the links in the page are no-follow. I read the FAQ section. It said if the hub score is less than 40 or hubberscore is less than 75, the links are no-follow. My hubscore is 48. But, my hubber score is 30. How do I increase my hubberscore? P.S: I use spun articles to submit content.
