No AdSense Ads Related to Sensitive Issues
In order to ensure a positive user experience and high quality standards in the advertisements we deliver, Google may reject ads related to topics that are considered a sensitive issue.
Google has modified its AdWords policy to prohibit AdSense ads which may be related to sensitive issues:
Sensitive issues are usually identified in response to exceptional global events, which can not be predicted and therefore are not mentioned here.
Incidents that affect our sensitive issues policy include natural calamities, tragic incidents or war / conflict situations.
Advertisements for news policies and charitable / relief / aid organizations are generally allowed under this policy.
