Someone has since reinstated the handle @cook99official to start up a new account, with the bio "I love when people get killed" and linking it to a YouTube account. with over 39,000 subscribers.

The tweet went viral, with more than 10,000 retweets. However, the photo was of YouTuber and Twitter user @TROTWOfficial, who replied to clarify:
