Yesterday Twitter announced that users’ phone numbers and email addresses were used for showing ads for the target audience. Also, the company confirmed that other personal data was not shared with advertisers and third-parties.

Also, in the Twitter’s blog it is said, “As of September 17, we have addressed the issue that allowed this to occur and are no longer using phone numbers or email addresses collected for safety or security purposes for advertising”.

Twitter didn’t tell how many people were impacted by this and made the apology. The company is trying to make sure that they don’t make a mistake like this again.

However, we want to remind you that it’s not the only mistake Twitter made. Just a month ago, the account of Twitter’s CEO, Jack Dorsey’s, was hacked. Two months earlier United States Federal Trade Commission fined Facebook on 5$ billion for transmission of personal data to Cambridge Analytica. It was the biggest fine for disclosure of personal data in history.
