It is true that hackers can potentially obtain and leak the email addresses of Twitter users.
There have been instances in the past where hackers have breached the security of websites or databases and obtained personal information, including email addresses, of users.
In some cases, this information has been made publicly available or sold to third parties.
To protect your personal information, including your email address, it is important to follow best practices for online security.
This includes using strong, unique passwords for all of your accounts, enabling two-factor authentication when available,
being cautious about clicking on links or downloading attachments from unknown sources.
