Who says adsense is unpredictable? I predict that next year there will be scammers advertising within adsense.
I concur with this.
I see for English content for visitors from US, UK, Canada, and Germany, that most ads are okay-ish. I'd say about 80% of the ads. As soon as you leave these territories, however, all the scammers show up.
