Confusion reigns around what can and can’t be said about abortion in different online spaces.

Motherboard reported Monday that Facebook was “removing the posts of users who share status updates that say abortion pills can be mailed, and in some cases temporarily banning those users.”

Meta, whose policies prohibit people from purchasing and selling “non-medical drugs, pharmaceutical drugs and marijuana” on the platform, said some posts were incorrectly removed.

Shout Your Abortion, a campaign that promotes abortion access and education, posted this week that Instagram was putting “sensitive material” warnings on posts mentioning abortion, abortion pills or criticizing the Supreme Court’s decision. (Instagram tweeted it was looking into sensitivity labels being incorrectly used.)
