A sock puppet is an online identity used for purposes of deception1 within an online community. It is a fake identity through which a member of an Internet community discusses or comments on oneself or ones work, pretending to be a different person, like a puppeteer2 manipulating a hand puppet.
坎肩是互联网社区中为了隐藏身份而注册的ID。这是一种不真实的互联网身份，平台或社区用户通过坎肩假装成另外一个人参与有关自己及自己作品的讨论或者评论，就像手偶演员操纵手偶表演一样。
Sock puppet英文本意为袜子木偶，最早出目前1959年。目前指出于欺骗目的而用的不真实互联网身份，譬如大家在互联网上常常用坎肩登录。
