If you haven't already heard of this site, tread carefully. Use common sense, and don't take anything here too seriously. They don't even take themselves seriously. Make sure you read the FAQ and rules if you plan on posting. A great place to waste time at. "Work-safe" boards tend to have relatively decent community.

4chan is by far a website that can be considered grossly inappropriate, immoral, and despicable to many people. However, the content of this site is so varied and offensive because unlike most websites, it provides virtual anonymity to the user and permits said user almost complete freedom of expression and opinion. While I do not recommend this website to anyone (and not only because of Rules 1 & 2), I do believe that this is one of, if not the, freest forums for discussion and conversation on the Internet. If you are someone who can tolerate copious and gratuitous amounts of pornography, gore, violence, offensive humor, and obscenities, you may just make it in 4chan. Just so long as you can tolerate child pornography, animal abuse, bestiality, scatophilia, and other various grotesque paraphilias, you may find this place not so bad. And lastly, if you can withstand a near-constant onslaught of racism, bigotry, contentiousness, trolling, hate speech, and unwarranted intolerance, then you very well may be able to push past the hellhole that is 4chan and see its true beauty. If you cannot, however, then stay away. Far, far away.
