Consumer-goods company Unilever will not work with social media stars, or "influencers," who buy followers on platforms such as Twitter and Facebook, it announced Monday.

Chief Marketing Officer Keith Weed said the company would scrutinize how it works with such influencers and urged other brands to look at how they avoid fraud on social media. The company has an overall marketing budget of more than €7bn ($8.1 billion).
