Facebook, Google limit robo systems that allowed racist ads

­­­­­­­­­­­Bloomberg

The world’s largest digital advertising companies reined in their automated money-making machines after the systems were shown to spit out ads based on racist and other offensive information.
Facebook Inc. shut off a key self-service ad tool, while Google stopped its main Search ad system automatically from suggesting offensive phrases for targeting. The moves are the latest sign of rising scrutiny of the largest US internet companies and how their software-driven services and ad businesses are influencing society.
The companies have thrived on their ability to offer targeted ads on a massive scale across huge audiences without much human intervention. This week, several news organisations showed they could buy ads based on racist and antisemitic terms or categories. The biggest advertisers are unlikely to run marketing campaigns like this, but it shows how these systems are open to abuse and may require more hands-on monitoring.
“These tools are so easy to use that, without trying very hard, it’s relatively easy to expose the downsizes of automated ad sales,” said Brian Wieser, a Pivotal Research Group analyst and critic of Facebook and Google.
Facebook said advertisers will no longer be able to target people by how they describe their education or employer after finding that some were filling in those fields with offensive content.
The social networking company will remove targeting by self-reported education, field of study, job title and employment fields in user profiles until it can fix the problem in its self-service advertising system.
Facebook software creates targeting categories for advertisers automatically, and the company adjusts them after problems are noticed by people. Facebook has run into similar issues with this type of reactionary enforcement before, both in its ad business and consumer-facing services. Its live video service has shown murders with enough time to go viral before being noticed by the company and taken down. Congress is investigating how Facebook’s ad systems were used, likely by Russia-based entities, to influence the 2016 US Presidential election.
Google’s AdWords system, one of the most-profitable businesses ever created on the internet, was found wanting in a similar way. It runs ads based on phrases, or keywords, that people type into the company’s search engine. This is very useful for companies selling shampoo or clothes. Flaws in Twitter Inc.’s automated ad system were also exposed too. The social media company’s site told marketers it has millions of users interested in terms like “wetback,” “Nazi” etc.
