Twitter announced that several email addresses and phone numbers uploaded by users to meet its security requirements may have been ‘inadvertently’ used for advertising purposes.
The company said that the issue was rectified as of Sept. 17, without revealing how many users were affected.
Social media companies, including Twitter and Facebook, have faced heat from users and regulators globally on how their platforms handle user data.
Twitter started when advertisers uploaded their marketing lists; it may have matched people on the platform to their list based on the email or phone number provided by account holders.
Twitter reported that the information was not shared with third parties, but was made available internally to allow users to receive targeted advertising
Twitter Users will no doubt be delighted that another tech giant hasn’t missed an opportunity to commercialize every bit of data it can—which in this case was security-related and so as poor as it gets.
The company publically came forward and announced, “When an advertiser uploaded their marketing list,” Twitter stated, “we may have matched people on Twitter to their list based on the email or phone number the Twitter account holder provided for safety and security purposes. This was an error and we apologize.”
