San Francisco: Facebook has launched a new tool for its users that will identify ads with inaccurate information or misrepresented products. The tool is designed to let people review businesses that they've made a purchase from, Facebook said in a blog post on Wednesday.

"We spoke with people who have purchased things from Facebook advertisers, and the two biggest frustrations we heard were that people don't like ads that quote inaccurate shipping times or misrepresent products," the company said.
