Facebook announced today that it will no longer allow advertisers to target users based on potentially “sensitive” topics like health, sexual orientation, or religious and political beliefs. “Lung cancer awareness,” “LGBT culture” and “Jewish holidays” are just some of the interest categories that will no longer be targeted starting early next year.

“The decision to remove these Detailed Targeting options was not easy and we know this change may negatively impact some businesses and organizations,” the company wrote in a blog post, saying input from civil rights experts, policymakers and other stakeholders contributed to its decision. Advertising revenue is Facebook’s leading source of income, so any major change to ad policy can have significant ramifications.
