This extension might come in handy when looking domains and links that may have issues with search engine penalties:
http://www.spamflag.com/An introduction
We produced this extension after working on literally hundreds of Penguin algorithmic/ manual actions (Google penalties) over the past few years. Like many of our peers we believe that manual link analysis the only way to determine if a link it manipulative, or not. Whilst we highly value the dozens of different metrics available to help make decisions about links, we truly believe that in order to be 100% certain about a link, it is essential to use them in combination with looking at the website/page in question.
