I just finished auditing a site where 90% of their backlinks are nofollow. I never saw anything quite like it. And yet, these are all apparently honest social media links and not company "plants". It's just that this is the way their market works and they've put little to no effort into attracting in-content links.
And though they could be ranking better, they do have a significant number of page 1 rankings, even position 1-2-3 for generic query terms.
