For those of you who don’t know: Google periodically cleans house in their AdWords program. They single out websites and assign them a poor “quality score”. These sites hit by this bad score have their minimum bid prices skyrocket to $5 or $10 per click. This effectively bans you from AdWords since most webmasters cannot afford to pay $10 for every click Google sends their way.
