I originally posted this in the Spam Update thread, but I think that maybe I should have posted it here.

I would appreciate your opinions.

For a site that I am working on, I have backlinks from forum signatures (forums related to niche of site). My posts, I would say, are informative but these backlinks are a good number of my overall backlinks.

The backlink is anchor text. For example, build metal widgets (build metal widgets is a phrase that I would like to rank for).

Could this be considered over optimization by Google Penguin?
