I'm trying to get rid of a Google penalty, but one of the URLS is particularly bizarre. Here's the penalized site: http://www.travelexinsurance.com. One of the external links Google cited as not being natural that links to the penalized site is: http://content.onlineagency.com/index.aspx?site=6599&tide=769006&last=3111516 In the backlink profile of the penalized site, there are about 100 different backlinks pointing to www.travelexinsurance.com from content.onlineagency.com/... So when I visit  http://content.onlineagency.com/index.aspx?site=6599&tide=769006&last=3111516 it actually is displaying content from http://www.starmandstravel.com/787115_6599.htm, which you can see after clicking the "Home" button. That company is a legit travel agency who I assume knows nothing about content.onlineagency.com and is not involved in whatever is going on. And that's the case for every link from content.onlineagency.com. So I'm just wondering if someone can help me understand what sort of tactic  content.onlineagency.com is using. One of my predecessors I fear used some black hat tactics. I'm wondering if this is a remnant of that effort.
