    i am using the check links function of scrapebox to filter out nofollow links but i still have some nofollow sites in my list

    right now i am using this tags for the site checker:
    rel=?nofollow?
    rel=?nofollow?
    rel="external nofollow"
    rel='external nofollow'

    what else nofollow tags shoud i add?
    how many nofollow tags exist and could you give me a link to a site that list all the different nofollow tags?

    thanks
