I rank number 2 for a very competitive keyword. Been there for months. This site was preBHW so its never had much black hat done to it. Recently Im noticing a lot more backlinks that I have not done myself. They are really crappy type comments and xrumer blasts, and ALOT of them. They are linking to inner pages as well as the home page. Im hoping to not lose my ranking, but there doesn't seem much I can do. Would high PR backlinks combat it? and is there anyway to make it stop?
