"We would ban this as quickly as a site that has pornography and violence," Zeitz says. Although Breitbart doesn't explicitly offer either, AppNexus says it incites violence and promotes hate speech through "either coded or overt language." The ban won't pull all advertising from the news site, however -- just some. According to Bloomberg, Breitbart never sold ad-space directly through AppNexus, but would be served ads from the company's customers through a variety of networks and exchanges.

This shouldn't come as too much of a surprise -- the publication's reputation for incendiary headlines has come under fire ever since it was reported that former Breitbart CEO Steve Bannon would have a place in President Elect Donald Trump's administration. Breitbart's current CEO seems to disagree with AppNexus' assessment, and told Bloomberg that the site "has always and continues to condemn racism and bigotry in any form." Fine words, though they do seem to contradict some of the site's most infamous headlines. It's a bit hard to reconcile a condemnation of bigotry with headlines that celebrate the confederate flag, condemn gay rights and use terms like 'renegade Jew.'
