Lets hope they are working to address the existing comments and the damage already done by blog spammers. Quite frankly I think these assholes should be hung from the nearest tree.
Its sad when the only way people can compete is to do it through Spam or cheating or by attempting to damage others with fake links. If these losers put the same time and effort and thought into building quality sites with useful and unique content the internet would be a far better place.
