Facebook owner Meta said he had removed a large number of groups and accounts sharing upskirting content after BBC News investigated the issue.
The TV report found images and videos of upskirting shared on the social media platform.
Some content reported to Facebook by the investigation was not immediately removed, with the site saying it did not appear to violate its community standards.
However, Meta said it has now taken action against groups, individual accounts and hashtags associated with the content.
Facebook’s adult exploitation policies do not allow the posting of secretly taken images of a real person’s body parts on the platform, including photos or videos that mock, sexualize, or embarrass the depicted person.
Upskirting was made a special offense in England and Wales in 2019.
In a statement, a Meta spokesperson said the company knows “our work on this is never finished.”
“Sharing intimate images without consent, including upskirting, is not allowed on Facebook.
“Following the BBC investigation, we removed a large number of groups and accounts and took further action to block several associated hashtags.
“We know our work is never done, and we will continue to remove any infringing content upon learning of it.”
Social media sites have been repeatedly criticized for their handling of harmful content online, and activists have called for more to be done to improve content moderation and user safety across platforms.
Tougher online safety laws are currently making their way through Parliament in the form of the Online Safety Act, which, once enacted, could see the biggest social media platforms face hefty fines or have access to their sites blocked if they do do not protect users from harmful content.
