Meta has removed or restricted dozens of accounts belonging to abortion access providers, queer groups and reproductive health organisations in the past weeks in what campaigners call one of the “biggest waves of censorship” on its platforms in years.

The takedowns and restrictions began in October and targeted the Facebook, Instagram and WhatsApp accounts of more than 50 organisations worldwide, some serving tens of thousands of people – in what appears to be a growing push by Meta to limit reproductive health and queer content across its platforms. Many of these were from Europe and the UK, however the bans also affected groups serving women in Asia, Latin America and the Middle East.

Repro Uncensored, an NGO tracking digital censorship against movements focused on gender, health and justice, said that it had tracked 210 incidents of account removals and severe restrictions affecting these groups this year, compared with 81 last year.

Meta denied an escalating trend of censorship. “Every organisation and individual on our platforms is subject to the same set of rules, and any claims of enforcement based on group affiliation or advocacy are baseless,” it said in a statement, adding that its policies on abortion-related content had not changed.
