很多商家TOS/AUP中禁止obscene的内容，有人问这是不是禁止成人内容的意思。

这里转载一段国外对于obscene与pornography区别的解释：

Although the terms obscenity and pornography are often used interchangeably, they are different. The obscene is something that is foul, filthy, or impure, especially when exposed to public view. Obscenity is a legal term of art that applies to certain depictions of sex that are not protected by the constitutional guarantee of free speech because they appeal to debased sexual desire rather than the intellect. In Miller v. California, 413 U.S. 15 (1973), the U.S. Supreme Court defined obscenity as material that is predominantly "prurient" (that is, appealing to impure sexual desire) according to contemporary community standards; is "patently offensive" in its portrayal of sexual acts; and lacks "serious literary, artistic, political, or social value" when considered as a whole. In essence, the concept of obscenity is limited to material depicting hard core pornography, which means graphic portrayals of ultimate sex acts or lewd exhibition of sexual organs.

大意为”obscene“特指缺乏文学、艺术、政治、科学、社会性的单纯色情内容。

举例来说拍摄大量生殖器官放到网站，却没有合理的解释，那就是违法。

如果说明这是医学参考或人体艺术，那就不违法。

说得够明白了吗？
