Google will warn Chrome users when they are visiting pages that use deceptive forms to sign visitors up for mobile subscriptions. Deceptive sites are asking users to enter their mobile information in order to access a game or other content. Google is adding a new Billing category to Safe Browsing that keeps track of sites that perform deceptive billing signups. When Chrome mobile, desktop, and Android WebView users visit a page that has been flagged as deceptive, they will be shown an warning interstitial that states “The page ahead may try to charge you money”””
