Copyright issues One of the central issues of Porn 2.0 is
copyright infringement. Porn 2.0 websites have been criticized as potentially harmful to the income streams of the traditional pornography industry such as DVD sales and website subscriptions.
Privacy The distribution of sexually explicit images or videos of individuals without their consent is called revenge porn. The practice began in
pornographic magazines in the late 20th century. The uploading of such images to the Internet to humiliate and intimidate people has become a significant societal issue in the 21st century. Uploading material without a model's consent is usually prohibited by a website's
terms of use, although some sites such as Voyeur Web allow non-consensual photos and move offices frequently to avoid the legal problems this might otherwise entail. Photos and videos of non-consenting models are often obtained through the use of
hidden cameras and the sexualization of their nudity. A woman taking a shower at a gym, for example, may be filmed without her knowledge and have the video distributed as pornography. ==Porn 3.0==
