The security researcher Karin Saini, found that the Twitter keeps the user's entire message history for years - even those that, in theory, have been deleted. Direct messages are a simple way for users to communicate with each other within this network.
According to the researcher, when accessing a file with her own information from Twitter, she obtained access to data and messages from accounts that had not existed in the platform for years. In addition, by using an existing vulnerability in one of the social networking APIs, it was possible to even access messages and tweets that had been deleted, something the researcher found worrisome.
Karan Saini confirmed another interesting fact. Messages sent to or from deleted or suspended accounts are still available. Still, it remains to know how Twitter will handle this situation.
In the tests done by the site TechCrunch, entering the settings of Twitter and to download your personal information, you can access everything the company has registered for your account - including conversations with users who have not been around for years on the platform.
In an official note, Twitter revealed that it would initiate an investigation into the matter, but that at the moment it would not make any comment on the findings of Saini.
In short, this is another situation that demonstrates that "once on the internet, forever on the internet". Although companies tell us that certain data has been erased, this is not always the case. This is just another example of this.
