Twitter admits misusing personal information for advertising purposes
As per company sources, third-party marketers may have been able to reach specific users on Twitter based on their personal information even if the user was not willing to do so.
Following the news, Twitter released a statement saying, "We cannot say with certainty how many people were impacted.”
Unusually, the company is not proactively contacting customers directly to inform them of the breach.
Twitter officials reveal that they are not sure when they discovered the issue but they had addressed the problem “as of September 17” - 21 days ago.
The firm said it was "no longer using phone numbers or email addresses collected for safety or security purposes for advertising”.
Twitter says that they have more than 139 million users and they are served with advert alerts on regular basis.
Earlier in March, another social networking site Facebook was highly criticized for using numbers and email addresses submitted for two-factor authentication to target advertising but unlike twitter, Facebook doesn’t consider it to be a mistake.
