He says he has already solved the problem and that numbers and email addresses were “involuntarily” provided
LOS ANGELES, Oct. 9 (DPA / EP) –
The Twitter social network has made its apologies public for having “involuntarily allowed” the sending of advertising to telephone numbers and email addresses that its users had provided solely for security reasons.
“We have recently discovered that when you provide an email address or a phone number for security reasons, for example for double-factor verification, this data may have been involuntarily used for advertising,” Twitter said, in a release.
The social network has said that this information has been used in its “ad systems for partner audiences and for personalized audiences”, which allows companies to send their ads to users based on the company's own marketing lists.
When an advertiser uploads their marketing list to the Internet, some users may be linked to those lists based on the data of the email address and their telephone number that they have provided solely for security reasons and not for sending advertisements.
“It was a mistake and we apologize,” Twitter said, before pointing out that it cannot specify the number of people who have been “affected” by this practice. The technology company based in San Francisco (USA) has insisted that it has not shared the data externally and that the problem was resolved on September 17.
“We are sorry that this has happened and we are taking steps to ensure that we do not make this mistake again,” Twitter said. The social network apologized in similar terms in July, when it admitted that it could have shared user data from its mobile application, including country codes and ad impact data, with advertiser companies even when users “had not given permission. ” to do it.
