Something that's bugged me for sometime is the fact that somehow lawyers can run ads for legal services and car manufacturers, tire manufacturers, etc can run all kinds of automotive ads via Adwords yet, these categories don't even exist on the Adsense category blocking tab. Same goes for downloadables which despite blocking any category remotely related to them, still seem to find their way onto my pages. Perhaps someone who uses Adwords has more insight into how ads are categorized and can shed some light on why I'm unable to categorically block certain subjects. What would really be great is a way to actually block these seemingly untouchable subjects but that may be asking way too much.
I guess a concrete question would be, does adwords actually offer a legal category and if so, why can't I block it in adsense? And, to be clear, I have third-party networks turned off so all of this should be Adwords related.
