这是网名不是备注
[zhè shì wăng míng bù shì bèi zhù]
'Zhe Shi Wang Ming Bu Shi Bei Zhu' directly translates to 'This Is a Username, Not a Remark.' It emphasizes that the chosen name serves as an identity rather than a description or note. This could be a statement about wanting to establish clear boundaries between what defines the user online versus how they are perceived.
