I also think that by having very little standards to accepting any publishers out there, even on free blog services, Google has diluted the earning power of existing, quality publishers. I think one should at least have their own domain name to put up ads. If you add MFA advertisers getting smarter with the system and stealing good business away from honest publishers, the general pressure on earnings, which wasn't there 3-4 years ago, is downward. One scalable solution is indeed to give publishers more control over bad advertisers, one not so scalable solution would also be to increase bans on low quality publishers.
