色情2.0，是以网路2.0为基础而命名，代表色情网站开始以“用户导向内容”为特色。网站可能会包含社群网站的特色，像是用户为本的分类，视讯、部落格，或是评论。这和传统的网路1.0内容完全相异。

色情2.0的网页会和主流的网路2.0网站一样，提供像是影像社群、社交网站、一般部落格，和影像传播等项目。

在一开始，色情2.0网站就大受欢迎，但同时也面对像是合法性等等诸多问题。在这些问题中，多半是关于数位著作权的问题以及相关衍生的合作伙伴广告问题。其他担忧则包含了分享与盗版之间的界线瘪及法律上大量免费的用户为本的色情内容所产生的后果。为了解决这些问题，以信用卡收费零元的认证措施已由分别由MaxPorn，RTA，以及PornoTube所采用。

对Porn 3.0来说，新闻媒体通常猜测会排除掉像是全息投影，而采用3D内容、多角度DVD、神经脉冲刺激、还有和电玩类似的多角度震动控制器

困境

即便有些人认为色情网站是产业的自然发展，也总是走在科技进步的前端，色情2.0也还是提出了一些困难与挑战。

版权议题

盗版是色情2.0面临最主要的挑战。色情2.0的网站常被传统色情产业抨击的是对产值有害，像是DVD销量和成人网站每月订阅数。

如同越来越多的大众网站一样，他们都在寻找更新更便宜的方法来填满他们的成人内容。多数大众也都在YouTube这类网站去观赏他们喜爱的节目片段、影像部落格、疯狂特技秀、和一些素人影片，于是成人取向的观众也渐渐远离了DVD和电视上的随选付费内容而投向像是Xview这类网站的怀抱。

就像YouTube一样，任何允许用户自行上传内容的网站都会有盗版的风险。随著网路2.0的进展，这一直是模糊的灰色地带，Viacom曾在2007年对YouTube求偿十亿美元的按键将这议题公诸于法庭，也对色情2.0的经营策略带来了巨大的影响。YouTube当年则是赢得了诉讼。

A 2007 decision by the 6th Circuit Court of Appeals found that the 2257 legislation was unconstitutional and violated first amendment rights. The decision was overturned in a 2009 en banc rehearing. The United States Supreme Court declined to hear the matter.

2007年美国第六巡回上诉法院发现了2257法条并无可适用之处，也违反了第一修正案的权力。但在2009年时的听证会又遭到翻盘，美国最高法院则拒绝对此提出管辖。

隐私问题

用户未经主角同意而上传内容是很有可能的，这也明文被使用条款所禁止。虽然有些网站像是Yoyeurweb允许上传未经主角同意的照片，而靠著经常移动办公室来避免所产生的法律问题。

获利来源

就像网路2.0会投资在Facebook、Myspace、和YouTube上，色情2.0上未发现商业上的获利策略。大量用户产生的内容导致伺服器的高费用，以及极少来自用户的低收入让色情2.0网站在经济上十分窘困。因为色2.0的服务目前多半是免费的，唯一的收入就是投放广告。当高流量的网站可以从广告获得稳定收入时，网站也在寻找其他新的商业模式。

RedTube

主条目：RedTube

RedTube is a Web 2.0, video-sharing, pornography site which in November 2009 held an Alexa ranking within the World's top 100 sites. However, by June 2010 it had fallen out of the top 100. Its popularity has been ascribed to its non-sexual name.

The site's database was accessed and temporarily shut down by Turkish hackers in February 2008.

YouPorn

主条目：YouPorn

YouPorn is a free pornographic video sharing site, similar in format to YouTube. It was started in August 2006. It was eventually overtaken by xHamster, Pornhublive.com and Livejasmin. The domain name was registered by a company in December 2005, and a little over a year later YouPornMobile was promoting mobile porn as well. The site was owned by MidStream Media International N.V., which was based in Willemstad, Curacao, a constituent country of the Kingdom of the Netherlands. However, it was later purchased by the large adult internet company, Manwin, which is owned by Fabian Thylmann, a German national residing in Belgium.

In October 2007, it was reported that a man living in California, had contacted Vivid Entertainment and AEBN in May 2007, claiming that he co-owned YouPorn with another individual, and was willing to sell for $20 million. He later denied owning YouPorn, claiming instead that it was founded and is operated by a German.

Porn 2.0 image websites

Various Porn 2.0 websites exist that have a majority of free promotional and user-generated material. A popular platform for 2.0 image websites is a Pinterest clone that is used by sites such as Sex.com and PicFapPin.com, which work the same way as other social media sites except that they are specialist on pornographic content only. Social Media sites that allow adult content include tumblr, Twitter, reddit, stumbleupon and PornToot.

Sites like Facebook and pinterest have a strict non-adult material policy and will remove and close any user account that posted such materials, as it is stated in their terms of service.

Alternatively to social media sites are free user-generated collections of pornographic material that finance their server costs by displaying advertisement, thus allowing them to share their content as an alternative strategy to the social media sites.

Social porn news

There are other forms of Porn 2.0, which do not involve user-generated video content. One is so-called "Social Porn" Digg-style websites, where registered users write articles about their submitted links.

Over-saturation due to free promotional material

Since the success of MET-Art starting in 1999, its success with free promotional material has created a constant source of new content on the internet and porn tube sites. Thus there is an ever-growing amount of free images and videos made available and shared through social media like Tumblr, Twitter and Stumbleupon. This therefore creates a whole new accessibility for pornographic material.

A strategy for paysites, in order to counter this growing movement, is to offer higher quality with high-resolution images and full-length Full HD videos, but revenue continues to shrink.
