Anonymous post

An anonymous post, is an entry on a textboard, anonymous bulletin board system, or other discussion forums like Internet forum, without a screen name or more commonly by using a non-identifiable pseudonym. Some online forums such as Slashdot do not allow such posts, requiring users to be registered either under their real name or utilizing a pseudonym. Others like JuicyCampus, AutoAdmit, 2channel, and other Futaba-based imageboards (such as 4chan) thrive on anonymity. Users of 4chan, in particular, interact in an anonymous and ephemeral environment that facilitates rapid generation of new trends.
