  • Read from the table image the post carries, rather than from its text. The post is the head of the thread whose later parts this file already cites: those parts restate the table in plain text, and the cells transcribed here are the ones no part reached. The researcher's own layout is what supplies the attribution -- a cell is headed with a Korean name and lists the aliases, accounts and addresses filed under it. The cell is headed "Ryu Un Song - Shopify", which is the researcher naming the platform the persona works on rather than an employer this site can verify.
