I agree with Kane. I would also like to add:
Whenever you have too many links of any 1 kind, it's a problem. Too Many Blog Links, Comment Links, Press Releases, Article Links, Directory Links, Contextual Links, Reviews, Guest Posts, Sponsorship Links, Infographics and so on...they are all links, they all count...follow links...nofollow links. All of them add up. That's what is a natural link profile. But when you have too many of a kind, it's very easy for bots to detect and that's where the problem is.
Makes sense ?
