Google relies on "we don't look until notified" and reaps income until notified.
There are enough complaints on the Adwords forum about sites being banned. G have the systems and the technology.
They are only getting blamed for this because the ads appeared on search. There was another "shock horror" story recently about inappropriate ads blaming the publisher (a high profile name) rather than the ad network.
When it comes to the games themselves I think graeme_p has expressed my views in a rather more moderate manner than I would use.
