NotATK

NotATK shows Albert Kim, better known online as ATK. Kim worked in Twitch's Korean operation and was Director of Korean Operations by 2013 before later serving as Twitch Korea's general manager. The command is a deliberately backward name joke: the man in NotATK is ATK himself.

His black rectangular glasses remain one of the portrait's clearest visual features, linking the chat face directly to the person behind the ATK handle.

Some viewers generalized NotATK into ethnicity-based stereotyping, especially around people wearing glasses. That later use came from chat communities, not Albert Kim, and should not be treated as the meaning of his portrait or as normal chat behavior.
