YouTube of porn: longitudinal measurement, analysis, and characterization of a large porn streaming service

A University of Auckland study by Cameron Wong, Yo-Der Song & Aniket Mahanti.

Abstract

Video content on user-generated content services has redefined entertainment and business on the Internet. Adult video streaming services have embraced this evolution to form YouTube style porn sites which combine the features of video hosting websites and online social media services.

This paper presents a comprehensive measurement study of one of the most popular new-age porn websites with social networking features, xHamster. Using active measurements, we have obtained metadata on almost 4 million unique videos that span the lifetime of xHamster from 2007 to 2018.

An analysis of this corpus allowed us to characterize the service and gain insights into the key players of the website including the website owners, video uploaders, and the viewers. By studying the characteristics of videos such as views, duration, the number of uploads, tags, ratings and comments, we give an overview of xHamster's current state, compare it to traditional and adult streaming services, and find the niche that xHamster occupies as an amateur content focused service.

We find that there are significant differences between adult streaming services and traditional streaming services. The injection rate of new videos is lower but the website does not need a large number of new uploads as long as the front page is constantly refreshed. The length of an average adult video is shorter than that of the average video on traditional streaming services, and we find that there is minimal engagement with ratings and comments. Video tags are actively used to organize and filter through content, and we observe that the more tags a video has, the more views it is likely to obtain.

The porn trade magazine AVN comments further about the research:

YouTube, according to the internet data site Alexa.com , is the second-most trafficked website in the world. The porn tube site xHamster ranks 111th . But content creators looking for engagement are much better off uploading porn to xHamster than posting a mainstream video on YouTube.

The study found that xHamster contains only a small fraction of the number of videos on YouTube -- about four million compared to YouTube's five billion videos. In addition, while xHamster users uploaded an average of 2,000 videos per 24-hour period, YouTube receives 500 hours of video uploads every minute.

But xHamster can get by with much less content, because viewers are hungrier for porn than they are for the variety of offerings on YouTube. According to the University of Auckland findings, an average YouTube video will be viewed 5,500 times. But an xHamster video receives an average of 68,000 views.

The study also showed that despite attempts around the world to ban it, porn only continues to grow in popularity. According to the study, between 2013 and 2017, the number of videos uploaded to xHamster increased by a factor of three.

A Japanese porn producer is opening a sexxx-rated adult theme park staffed with starlets.

SOD Land (Soft on Demand) is slated to open Oct. 10 in five floors of a complex of bars and entertainment venues in the Kabukicho red-light district of Tokyo's Shinjuku Ward next month.

In the basement, newly minted porn starlets will staff the space, while industry vets will serve drinks on the third floor, Syain Bar Kabukicho, described as a space of dreams.

On the second floor, women from the commercial sex industry are featured. The fourth floor is the Silent Bar where porn stars clad in bikinis can be gawked at by customers through a one-way mirror.

On the first floor is a souvenir shop loaded with porn DVDs, sex toy machines and a photo booth.

Soft on Demand boss Yoshiaki Nomoto said the establishment had been on the drawing board for some time.

Abstract

Whether pornography contributes to sexual aggression in real life has been the subject of dozens of studies over multiple decades. Nevertheless, scholars have not come to a consensus about whether effects are real.

The current meta-analysis examined experimental, correlational, and population studies of the pornography/sexual aggression link dating back from the 1970s to the current time.

Methodological weaknesses were very common in this field of research. Nonetheless, evidence did not suggest that nonviolent pornography was associated with sexual aggression. Evidence was particularly weak for longitudinal studies, suggesting an absence of long-term effects. Violent pornography was weakly correlated with sexual aggression, although the current evidence was unable to distinguish between a selection effect as compared to a socialization effect.

Studies that employed more best practices tended to provide less evidence for relationships whereas studies with citation bias, an indication of researcher expectancy effects, tended to have higher effect sizes. Population studies suggested that increased availability of pornography is associated with reduced sexual aggression at the population level.

Porn superstar Mia Khalifa has changed her mind about wanting to be a porn star and is campaigning to get her videos taken down seemingly claiming some sort of retrospective withdrawal of consent. Of course all the videos were properly licensed for distribution and the licence holders are not keen on losing a significant revenue stream.

Porn company BangBros are most effected and so are contesting claims that Khalifa had only a short 11 film porn career. Now BangBros have responded with a list of 28 films that feature Khalifa.

Khalifa porn collector's may be interested in knowing the films required for the complete collecton. Based on BangBros' list, Khalifa made seven videos for Scoreland, two for John Stone XXX, one for TR Productions and 18 for Bangbros for a total of 28 videos. The total count has 17 more videos than what Khalifa claimed.

Khalifa also said she only made $12,000 from her short stint. However, in BangBros' responded that the company paid her $178,000. The adult site also debunked her claim that she was only a part of the porn industry for three months because she allegedly started in mid-2014 and only left in July 2017.
