The struggle to shape the experiences young people have online is now part of modern parenthood. As children and teenagers spend increasing amounts of time online, a significant share of parents and guardians now use Internet filtering tools (such as parental controls) to protect their children from accessing sexual material online.
However, new research from the Oxford Internet Institute, University of Oxford has found that Internet filtering tools are ineffective and in most cases, were an insignificant factor in whether young people had seen explicit sexual content.
Though the use of Internet filtering tools is widespread, there has been no conclusive evidence on their effectiveness until now. "It's important to consider the efficacy of Internet filtering," says Dr Victoria Nash, co-author on the study. "Internet filtering tools are expensive to develop and maintain, and can easily 'underblock' due to the constant development of new ways of sharing content.
Additionally, there are concerns about human rights violations -- filtering can lead to 'overblocking', where young people are not able to access legitimate health and relationship information."
The research used data from a large-scale study looking at pairs of children and caregivers in Europe, comparing self-reported information on whether children had viewed online sexual content despite the use of Internet filtering tools in their household. A second preregistered study was then conducted looking at teenagers in the UK.
Results of the research indicate that Internet filtering is ineffective and insignificant to whether a young person has viewed sexually explicit content. More than 99.5 percent of whether a young person encountered online sexual material had to do with factors beside their caregiver's use of Internet filtering technology.
"We were also interested to find out how many households would need to use filtering technologies in order to stop one adolescent from seeing online pornography," says co-author Professor Andrew Przybylski. "The findings from our preliminary study indicated that somewhere between 17 and 77 households would need to use Internet filtering tools in order to prevent a single young person from accessing sexual content. Results from our follow-up study showed no statistically or practically significant protective effects for filtering."
"We hope this leads to a re-think in effectiveness targets for new technologies, before they are rolled out to the population," says Nash.

Athletes who drink chocolate milk during exercise or after a hard workout may recover just as quickly as they would with sports drinks, a research review suggests.
What people eat and drink during intense exercise and afterward can impact how well their muscles recover and how rapidly their body replaces fluids and electrolytes lost during the workout, previous research has found.
Most studies assessing whether drinks with carbohydrates and electrolytes, or with protein, might aid recovery have been too small to draw firm conclusions about which beverages are the best option, the authors of the new review write in European Journal of Clinical Nutrition.
For their analysis, the researchers examined data from 12 small studies that compared how chocolate milk influenced several markers of exercise recovery, compared to a placebo beverage or a sports drink.
Athletes did exercise tests - mostly running or cycling - and then researchers looked at recovery markers like how long it takes to become exhausted during workouts, athletes' perceived exertion levels, heart rate and levels of lactic acid and an enzyme known as creatine kinase in the blood - which both rise with intense activity.
Overall, the study found that chocolate milk lengthened time to exhaustion, and improved perceived exertion, heart rate or levels of lactic acid in the blood at least as much other beverages.
"Chocolate milk contains carbohydrates, proteins, fats, flavonoids, electrolytes, and some vitamins which make this drink a good choice for recovery in athletes," said senior study author Dr. Amin Salehi-Abargouei of Shahid Sadoughi University of Medical Sciences in Yazd, Iran.
In some instances, chocolate milk appeared better than alternative drinks, the researchers report.
Time to exhaustion with chocolate milk drinkers was almost 1 minute longer than with nutrition-free placebo beverages and about 6 minutes longer than with sports drinks.
Lactic acid levels, an indication of exertion, were lower for chocolate milk drinkers than for people who consumed placebo drinks, the study also found.
"The take-home message is that chocolate milk is a low-cost, delicious, and palatable option for recovery and provides either similar or superior effects compared with commercial drinks," Salehi-Abargouei said by email.
The research was published in the European Journal of Clinical Nutrition.

With scarcely the kind of attention other sports marketing endeavors are receiving, esports is growing into a major platform for marketers. New research from Parks Associates shows that 10% of U.S. broadband households watch esports content on sites ranging from Amazon’s Twitch to YouTube, and 62% actually play an esports game for at least an hour a week.
"Esports is currently a niche market, but it has the ability to engage often hard-to-reach demographics," says Hunter Sappington, a Parks research analyst, in comments accompanying the latest report.
"Esports is a young, dynamic, and fast-growing industry. While viewership of many traditional sports is waning, esports is well positioned to capture the attention of a generation that grew up playing video games.”
In some ways, esports is a perfect reflection of how sports and leisure changed with the internet: the report says 67% of viewers use computers to watch esports, followed by 45% using TVs and 34% using a smartphone.
Indeed, “real” sports and esports have twinned seemingly easily.
This year, the NBA helped start its own esports offshoot called the 2K League with partner Take-Two Interactive, with 17 teams competing in the first season that started in May.
Some brands have been quick to react. The Samsung Galaxy Pro-Game team has been a powerhouse in the League of Legends championship series. Coca-Cola, LG, Intel and IBM earned street cred with gamers by sponsoring major events.
Parks says the typical gamer is under 35 and, not surprisingly, up on the latest video trends and technology. They spend an average $47.23 on non-pay-TV video entertainment, the new study says, compared to just $22.97 for non-gamers.
