For example, I frequently get email messages from people I know, but haven’t talked to in a while. Invariably the email subject is blank or says nothing but, “Re:”. Sometimes the email includes a suspicious attachment. And I sigh and delete the message, because I know these unused accounts have been hijacked from their unsuspecting owners and are now controlled by hackers.
But hijacked accounts go beyond mere annoyance. They are often used to hack other, juicier targets, making it more difficult for such electronic attacks to be traced back to the perpetrator. They can also be used in online financial scams, such as the “I’m stuck overseas and need you to wire me money” scam. Such scams appear far more realistic when they come from a seemingly-legitimate source like a friend’s email address rather than some random account, and many people fall for the trick.
Hijacked accounts can also be used to hijack other accounts like Facebook, Twitter, or even your bank account, if it’s been linked to them. It’s like a stepping stone to the rest of your stuff.
For these reasons, you should always delete old accounts if you are no longer using them. If you’re concerned that someone will take your old username, I recommend maintaining your old accounts by logging into them every few months and using strong passwords that have not been used on any other site.
You will need your username and password for the account you wish to delete. If you don’t have it, you typically need to follow the site’s procedures to recover a forgotten password before you can continue the deletion or deactivation process. Don’t forget to remove the deleted address from other accounts if it’s been linked to them, such as an old email address linked to your Facebook account.
You should note, however, that just because a site claims your account has been deleted, it may not necessarily have been. Many sites retain old accounts in case you want to reactivate them later. Also, your data may not be deleted even if you request it. Over the years any information you’ve stored online has doubtless been copied to untold backups and mirror servers. In reality, once your data is on the Internet, it’s out there forever. But at least by deactivating or deleting your accounts, you can help keep them (and the data they contain) from being used for nefarious purposes.
