The concept of the anonymous board was born on the Japanese site 2channel in 1999. The essential idea is that every poster is completely anonymous. The board may be strictly text only or image and text (commonly referred to as an imageboard).
This means the site has no registration and no barriers, anyone can post at any time instantly; in addition to this, anyone may view any part of the site freely without attaching themselves to a specific name. Beyond the ease of user, users can no longer be judged by their name and instead can only be judged by their individual comments. Hiroyuki, the creator of 2channel, said this in regard to anonymous posting:
Another reason to begin posting on anonymous boards is the unique community and sense of humor all boards seem to have. The ability to post anonymously allows for people to voice what they really feel or make comments/jokes about things that are normally taboo. They also develop numerous inside jokes (often called memes) which one will find often become more humorous than any normal joke could.
Not all anonymous boards are like 4chan, in fact 4chan originally wasn't even like it is now. The "anonymous" identity currently present in 4chan's /b/ is not at all what Anonymous is. Anonymous is simply a blank name used to represent a user on some boards (see Common Terms for other commonly used names); however, an influx of new users to 4chan's /b/ has left it completely confused and misguided. 4chan's "anonymous" identity that appears at Scientology protests and holds raids on other sites is the exact opposite to what real anonymous posters are like. Please do not look at 4chan's /b/ as an example of what anonymous boards are like!
Forget everything you learned posting on a regular forum/board This is something you MUST do. Anonymous boards are NOT like the rest of the internet. You must come onto an anonymous board with an open mind and a willingness to spend time reading posts BEFORE posting yourself. There is an expectation that you will conform to and learn the board's culture. A common example is emoticons; many users are used to making emoticons such as ^_^ or =) but these are generally frowned upon and are usually seen as a sign of immaturity. You can learn all of this and more by reading the air of the board. Also remember ANYTHING can be posted thus chances are you will be offended in some way. After visiting anonymous boards for a while you will begin to be less offended and see why it is silly to be offended by anything as you probably have thoughts you don't say aloud in person that are also offending to others.
"Lurking" is the most important part of becoming a successful poster. Each and every board has its own unique culture (generally rooted in 2channel one way or another). It is your job to learn it BEFORE making any posts. This process may seem daunting as boards do not have a set of defined parameters for posting. The only way to learn what sort of posts will be enjoyed is to spend time reading other posts. You will slowly learn all of the injokes, common posting style and sense of humor of the board as you read more and more posts. Do not make a post asking about the meaning behind an injoke or other questions about the board unless you absolutely have to as most users will be annoyed by this and simply tell you to lurk more. In addition to this, DO NOT make an introductory post or anything of the sort you should simply become a fellow poster overtime. Obviously this also means that, while posting as Anonymous, your work and your posts might never be directly attributed to you, regardless of the effort you put in them. Lurking can sometimes take only a week and other times take a few months. You'll know you're ready when you're understanding posts and finding the humor in them. Not all boards revolve around humor but there is always lurking to done just to make sure you aren't posting in a style that the others find annoying.
After you understand the board and how to post let your creativity run wild! Make witty posts, insightful posts, and any other enjoyable posts you want to make! But, before you post ask yourself "Will other users enjoy my post?" if the answer is no you shouldn't post it. Also do not make posts just to make yourself look good. This is an ANONYMOUS board the point is to not be identifiable you can tell us a story about your girlfriend that's INTERESTING or HUMOROUS but don't just make a post saying Hi I have a girlfriend and we have sex all the time.
Many anonymous boards provide a "name" field. Anonymous boards are not just about the software allowing users to post anonymously, it is a cultural thing: on an anonymous board, you are simply expected not to fill in the field if your identity is not relevant to the discussion. Some sites use anonmyous board software, but regulars always post under a nickname. Sometimes, as a result, board administrators disable the name field.
Where the line is drawn between "anonymous boards" and "boards where you may post anonymously" is sometimes a little fuzzy, but this document is only about boards where the overwhelming majority of posts are made anonymously.
In anonymous boards, names are used only when the identity of the speaker is relevant to the discussion. It doesn't have to be a nickname: on some sites, you will see people using "OP" as their name, to indicate that they are the Original Poster of the thread.
To avoid impersonation when this risk matters, a tripcode system is frequently provided by the site: add a '#' followed by up to 8 characters at the end of the name field, and the part after the '#' will be displayed in a crypted form. For example, typing "IMPORTANTGUY#tripcode" in the name field will show up as "IMPORTANTGUY!3GqYIJ3Obs" in your posts. You don't have to use a name, a tripcode can be used alone. ("#tripcode" ? "!3GqYIJ3Obs")
Moderators and administrators often use tripcodes when discussing site issues, but in addition of tripcodes their name may be displayed in a different color from regular posters, so that users do not have to verify the tripcode to know that the message comes from the people in charge of the site.
If you actually need to use a tripcode, you will first need to know a few things:
Here is a good rule to pick a strong tripcode: make your tripcode exactly 8 characters long, with a few random, meaningless letters, a few random, meaningless numbers, and some of the following symbols: $ - + / ; @ ^
Examples: #f6/a8@g9, #uh-1-m13, #vbv3$$44
Most importantly, have fun and ENJOY your board. I think everyone will find that once you are a part of an anonymous board it will be very difficult to go back to the regular internet as there is not a community quite like this anywhere else. You won't regret it!
