rish3, I agree. Also don't forget the huge number of genuine small businesses that got hit with Panda/Penguin that simply disappeared or relaunched, but without spamming. All these sites are nowhere in the SERPs now - even less competition for spammers. So we find ourselves in a situation where the "high street" is being occupied by brands and fly-by-nighters and genuine businesses are trying to sell their wares (that people do want) in some obsure alleyway nobody ever walks down.
