There is no issue with nofollow links

They are actually quite important for Google, as if you're site was an authority in the niche and would grow "naturally", it's only normal that it has both dofollow and nofollow links.

If you only focus on dofollow links and have way too many and almost no nofollow links, that's a red flag for Google and most probably will hurt you in the long run. Think of "dofollow" links as a trap that Google has set for search engine optimizers, to see who will spam them for "unnatural growth"

No they are not.

Whoever told you that had no idea what they were talking about.

I wish to have the same problem :-)
No follow links are not spoiling anything. They increase your rank, Google count them with small weight
