Twitter 'fesses up to more adtech leaks

Twitter has disclosed more bugs related to how it uses personal data for ad targeting that means it may have shared users data with advertising partners even when a user had expressly told it not to. Back in May the social network disclosed a bug that in certain conditions resulted in an account’s location data being shared with a Twitter ad partner, during real-time bidding (RTB) auctions. In a blog post on its Help Center about the latest "issues" Twitter says it "recently" found, it admits to finding two problems with users' ad settings choices that mean they "may not have worked as intended".
