Imageboard
From SNCApedia, the shit nobody cares about encyclopedia
Imageboards are a species of website invented by a few gooner basement dwelling japs in the 90's. The premise is that all posts on an imageboard are anonymous and eventually fall off the last page resulting in its deletion. There are no accounts nor any need to use a username in order to post. The only way to save posts is by using an archival extension or website.
However, you CAN give yourself a pseudoanonymous name or “namefag” which you can protect using a password or “tripfag”.
