Sit-In! is an activist browser-extension that extends and documents a physical sit-in organised by tech workers in Nairobi 2023. Install to join this digital sit-in in solidarity with the fight against the exploitative working conditions imposed by Meta and its subcontractors!
▶
Developed in collaboration with former Facebook content moderators in Nairobi, the project confronts the exploitation inherent to digital services, where low-paid moderators are tasked with filtering the Internet’s most toxic content, often at great personal cost.
The participating moderators are part of a landmark legal case against Meta - the first of its kind in which a Global South workforce is holding a tech giant accountable in a national court.
Sit-In! is a tool powered by the voices of this largely invisible workforce. When activated, the extension blocks the view of Meta's social media platforms, instead overlaying statements from the former content moderators. These statements bring our hidden labour into view, sharing our stories, dreams, and demands to expose the systemic exploitation embedded in Big Tech. Sit-In! turns the interface into a platform for protest.
Join our movement, install the extension, and help make invisible labour visible - Sit-In!

Sit-In! is a digital tool of resistance, inspired by a courageous protest led by Facebook content moderators in Nairobi in May 2023. The tool offers front-end users a glimpse into the hidden labour behind Facebook’s seamless interface, while also enabling them to show solidarity with the workers who make these platforms possible.
Sit-In! is a browser extension, a small software add-on, that transforms your web browser into a tool for digital protest.
Once installed, the tool blocks Facebook and other Meta services, and replaces them with statements from former content moderators in Nairobi. Hovering over these messages reveals more of their stories: the exploitation they endured, and the resistance they continue to lead.
The extension disables Facebook’s standard toolbar and replaces it with the Sit-In! icon, which displays the number of people currently participating in the protest.
Clicking the icon takes you to this website that anonymously tracks and displays real-time global participation, transforming individual actions into a collective act of solidarity.
Sit-In! takes its name and inspiration from a powerful real-world event: In May 2023, one hundred twenty former content moderators staged a sit-in at the offices of Meta’s subcontractor, Sama, in Nairobi. These workers had been abruptly fired just months earlier, shortly after organizing for better working conditions.
Recruited largely from impoverished communities across Africa, the moderators were tasked with reviewing and removing some of the most disturbing content on Facebook - including graphic violence, hate speech, and abuse. They worked long hours for low wages, with little to no mental health support. When they began organizing for fairer treatment, they were collectively dismissed. Despite a Kenyan court issuing a preliminary ruling in their favor, including provisions for compensation and healthcare, Meta and its subcontractor failed to comply. In response, the workers returned to the company’s premises in a bold act of resistance: a sit-in.
The footage in the background of this site reveals how the sit-in disrupted business as usual: The workers gathered as a flash-mob outside Meta’s subcontractor in Nairobi, singing and waving court orders. Bystanders looked on, and major media outlets, KTN, Citizen TV, Voice of Africa, even the BBC, covered the protest. The action pierced corporate silence, exposing the hidden toll of content moderation and amplifying the workers’ voices.
Yet much of the focus stayed on the subcontractor, leaving Meta/Facebook largely untouched.
Now two and a half years later, as of autumn 2025, the situation remains dire. Most of the former moderators are unemployed, impoverished, and traumatised. Meta, meanwhile, has evaded accountability by claiming it cannot be held liable in Kenyan courts and has since shifted its operations to another African country.
Nevertheless, in late 2024, a Kenyan court ruled that the case could proceed, and that Meta can indeed be held accountable in Kenya. The workers' fight, therefore, continues.
Inspired by the content moderators’ initial protest, the artistic software tool Sit-In! explores how digital interventions can challenge the structural barriers that allow Big Tech to avoid responsibility. It amplifies the voices of data workers and bridges the gap between back-end labour and front-end users. By disrupting the illusion of seamless browsing, Sit-In! compels users to confront the hidden human cost of content moderation, the very labour that keeps their feeds clean.
By engaging with Sit-In!, you join this movement. You take part in the struggle for justice and accountability, helping to make visible the workers who have been invisible for too long.
You can join Sit-In! simply by installing the Firefox browser extension from its official page on Mozilla Add-ons. Once installed and enabled, the extension automatically connects you to the protest.

Sit-In! does not collect any personal data: no names, emails, locations, or browsing histories. When the extension is active, it sends a simple, anonymous signal to the project’s server to indicate participation. This signal includes a randomly generated session ID (not tied to you or your device) and a timestamp. This allows the counter to display how many users are actively participating at any given time without compromising your privacy.
