Twitter is a social media platform that allows users to communicate with each other. It is also a great way to stay in touch with friends and family. However, there are some things you can do to be sure that someone has deleted their Twitter account. The first thing you should do is check the account history. This will show you when the person last used Twitter and what topics they were talking about. If the person has not used Twitter for a while, it might be worth checking their timeline to see if any new posts have been made. If the person has deleted their Twitter account, it might be worth checking their email to see if there was an email sent out from the company asking them to stop using the platform. If there was not, then it might be because they are no longer alive and have no connection to Twitter anymore.
