To add to that to people who don't know your quality score for a page in adwords is somewhere between 1 and 10, so someone with a page rank of 10 gets ads cheaper than those with a lower quality score. A score of 1 is basically googles way to signal to a site for whatever reason that they don't like what you are doing. Usually unless you can get the original decision overturned the domain will forever sit at 1 and be basically useless in terms of using adwords.
