Meta has taken down tens of thousands of Instagram accounts from Nigeria as part of a massive crackdown on sextortion scams. The accounts primarily targeted adult men in the United States, but some also targeted minors, Meta said in an update.

The takedowns are part of a larger effort by Meta to combat sextortion scams on its platform in recent months. Earlier this year, the company added a safety feature in Instagram messages to automatically detect nudity and warn users about potential blackmail scams. The company also provides in-app resources and safety tips about such scams.

According to Meta, the recent takedowns included 2,500 accounts that were linked to a group of about 20 people who worked together to carry out sextortion scams. The company also took down thousands of accounts and groups on Facebook that provided tips and other advice, including scripts and fake images, for would-be sextortionists. Those accounts were linked to the Yahoo Boys, a group of “loosely organized cybercriminals operating largely out of Nigeria that specialize in different types of scams,” Meta said.

Meta has come under particular scrutiny for not doing enough to protect teens from sextortion on its apps. During a Senate hearing earlier this year, Senator Lindsey Graham pressed Mark Zuckerberg on whether the parents of a child who died by suicide after falling victim to such a scam should be able to sue the company.

Though the company said that the “majority” of the scammers it uncovered in its latest takedowns targeted adults, it confirmed that some of the accounts had targeted minors as well and that those accounts had also been reported to the National Center for Missing and Exploited Children (NCMEC).
