4chan is described as an English-language image-board website. Essentially it is an online forum where users are able to post anonymously and search for specific content.
Users do not need an account or a username and so it is difficult to establish a social relationship using the site unless someone shares contact information. Content which has been posted (threads) expire after a certain amount of time.
The site explains that there are bulletin boards dedicated to a variety of topics from Japanese animation and culture to video games, music and photography. There are also boards for adult and NSFW (not safe for work) content.
The site has attracted some negative press coverage in 2014 as the site where nude images of celebrities were first shared after they had been hacked.
