The name Anonymous itself is inspired by the perceived anonymity under which users post images and comments on the Internet. Usage of the term Anonymous in the sense of a shared identity began on imageboards. A tag of Anonymous is assigned to visitors who leave comments without identifying the originator of the posted content. Users of imageboards sometimes jokingly acted as if Anonymous were a real person. As the popularity of imageboards increased, the idea of Anonymous as a collective of unnamed individuals became an internet meme.
Anonymous broadly represents the concept of any and all people as an unnamed collective. As a multiple-use name, individuals who share in the "Anonymous" moniker also adopt a shared online identity, characterized as hedonistic and uninhibited. This is intended as a satirical, conscious adoption of the online disinhibition effect.
