4chan is an imageboard website where users can anonymously post images and comments on a wide range of topics. It was created in 2003 by Christopher Poole and was initially inspired by the Japanese 2channel.net. The site is divided into numerous boards, each with its own theme, ranging from video games, movies, and music to more controversial subjects.
The phrase typically refers to the most active, archived, or "best of" discussions within 4chan’s subculture dedicated to Adult Baby/Diaper Lovers (ABDL). To understand this niche, one must look at how 4chan—a site known for its chaotic anonymity—handles a community centered on age regression and paraphilic infantilism.
