In its ambitious mission of documenting all human knowledge, Wikipedia contains many thousands of articles on a vast array of topics. A relatively small fraction of these topics are frequently censored by educational, governmental, corporate, parental and other filtering schemes.
- Some Wikipedia articles discuss words or language that are considered profane, vulgar or offensive by some readers. See Wikipedia:profanity for more information.
- Wikipedia contains many different images, some of which are considered objectionable or offensive by some readers. For example, some articles contain graphical depictions of violence, or photographs of human anatomy.
- Many articles contain frank discussion of controversial topics. Some subjects that are discussed have criminal applications in some jurisdictions. Others contain information on dangerous or otherwise risky activities (see Wikipedia:General disclaimer and Wikipedia:Risk disclaimer).
- Wikipedia contains spoilers
- Wikipedia may contain triggers for people with post-traumatic stress disorder
- It should be noted that as Wikipedia is open to contributions from the public, there may at any time be graffiti present on the Wikipedia.
- There may be medical, legal or other information that is normally also the subject of professional opinions; Wikipedia is not a substitute for seeking the help of a professional. Please note: Wikipedia does not give legal advice or medical advice.
Wikipedia's current policy is to include such content, provided it breaches neither any of our existing policies (especially Neutral point of view), nor the law of the state of Florida in the United States, where the server is hosted. See taboo articles and list of controversial issues for some examples of articles that may contain such content. Some of these articles contain warnings, but many do not.
Wikipedia contains obscure information that would not be covered in a conventional encyclopedia. Wikipedia's coverage of subjects is patchy, based on the whims of its contributors. Readers should not judge the importance of topics based on their coverage in Wikipedia, or assume that a topic is important merely because it is the subject of a Wikipedia article.
