New guidelines have urged social media platforms to curtail internet “pile-ons” to better safeguard women and girls online.

Ofcom, Britain’s communications regulator, implemented guidance on Tuesday aimed at tackling misogynistic abuse, coercive control, and the non-consensual sharing of intimate images, with a focus on minimizing online harassment of women.

The measures imply that tech companies will limit the number of responses to posts on platforms like X, a strategy Ofcom believes will lessen incidents where individual users are inundated with abusive responses.

Additional measures proposed by Ofcom include utilizing databases of images to prevent the non-consensual sharing of intimate photos—often referred to as ‘revenge porn’.

The regulator advocates for “hash matching” technology that helps platforms remove disputed images. This system cross-references user-reported images or videos with a database of illegal content, transforming them into “hashes” or digital identifiers, enabling the identification and removal of harmful images.

These recommendations were put forth under the Online Safety Act (OSA), a significant law designed to shield children and adults from harmful online content.

While the advice is not obligatory, Ofcom is urging social media companies to follow it, announcing plans to release a report in 2027 assessing individual platforms’ responses to the guidelines.

The regulator indicated that the OSA could be reinforced if the recommendations are not acted upon or prove ineffective.

“If their actions fall short, we will consider formally advising the government on necessary enhancements to online safety laws,” Ofcom stated.

Dame Melanie Dawes, Ofcom’s chief executive, has encountered “shocking” reports of online abuse directed at women and girls.

“We are sending a definitive message to tech companies to adhere to practical industry guidance that aims to protect women from the genuine online threats they face today,” Dawes stated. “With ongoing support from our campaigners, advocacy groups, and expert partners, we will hold companies accountable and establish new benchmarks for online safety for women and girls in the UK.”

Ofcom’s other recommendations suggest implementing prompts to reconsider posting abusive content, instituting “time-outs” for frequent offenders, and preventing misogynistic users from generating ad revenue related to their posts. It will also allow users to swiftly block or mute several accounts at once.

These recommendations conclude a process that started in February, when Ofcom conducted a consultation that included suggestions for hash matching. However, more than a dozen guidelines, like establishing “rate limits” on posts, are brand new.

Internet Matters, a nonprofit organization dedicated to children’s online safety, argued that governments should make the guidance mandatory, cautioning that many tech companies might overlook it. Ofcom is considering whether to enforce hash matching recommendations.

Rachel Huggins, co-chief executive of Internet Matters, remarked: “We know many companies will disregard this guidance simply because it is not legally binding, leading to continued unacceptable levels of online harm faced by women and girls today.”
