Twitter is asking a judge in the U.S. District Court in the Northern District of California to dismiss a class-action complaint claiming the company collected users’ contact data for security purposes and used it for advertisement targeting, MediaPost reports. The company said its use of the data was consistent with its privacy policy and that it “did not sell — or even disclose” the plaintiff’s information to advertisers. The complaint follows the U.S. Federal Trade Commission’s $150 million fine against Twitter for the alleged deceptive data collection.
