Why Are Facebook And Google Trying To Stop Online Adultery?

AshleyMadison.com, the largest online “dating” site made for adulterers, has their advertising actively blocked by Facebook, Google and Microsoft. They’re not letting the site buy keywords and ads, even though they let competing sites do so. What’s weirder, Facebook even blocked the URL for ashleymadison.com in Facebook messages temporarily, saying it was used in spam. [The Atlantic]
