>Instagram is coordinating with other social media platforms, including Twitter and TikTok, to ban users who have been involved in stealing hundreds of single-word user names. These short, covetable handles, known as “O.G. user names” (think keywords like [@Killer](/user/profile/Killer) , [@Sick](/user/profile/Sick) and [@Miracle](/user/profile/Miracle) ), are valuable because they are eye-catching and confer status; the people who first snatched them up were early adopters. Cybercriminals buy and sell the user names on dedicated forums and messaging apps.
