I've noticed that a lot of sites seem to have a lot of the types of backlinks that you'd think would have been hurt by penguin... yet they are still going strong. http://www.legalbuds.com/ for instance I noticed because they were showing up in TBS as a synonym for a lot of VERY random terms (I'm not even spinning anything related to that niche, words like "I've" popped them up). So I looked and while I think a lot of the links look not super HQ they are still doing ok. Why is this? Am I missing something or does google just not pick on some sites? Maybe age of the site?
