The samples I was given are:
1. a forum profile link with keyworded anchor text - which the SEO company I contracted did plenty of. Not that I knew of this technique, until I started looking at the backlinks after the penalty was applied. Thing is I have no way of removing them without the logins, so I'm screwed.
2. 2 examples of articles which seem legit but have keywords in the links. These have contact details but article sites in general are not very receptive to removing links from articles, that is if they have contact details. Many don't.
