NEW YORK, July 25 (Reuters) - Meta's Oversight

Board on Thursday said the company's rules were "not

sufficiently clear" in barring sexually explicit AI-generated

depictions of real people and called for changes to stop such

imagery from circulating on its platforms.

The board, which is funded by the social media giant but

operates independently, issued its ruling after reviewing two

pornographic fakes of famous women created using artificial

intelligence and posted on Meta's Facebook and Instagram.

Meta said it would review the board's recommendations and

provide an update on any changes adopted.

In its report, the board identified the two women only as

female public figures from India and the United States, citing

privacy concerns.

The board found both images violated Meta's rule barring

"derogatory sexualized photoshop," which the company classifies

as a form of bullying and harassment, and said Meta should have

removed them promptly.

In the case involving the Indian woman, Meta failed to

review a user report of the image within 48 hours, prompting the

ticket to be closed automatically with no action taken.

The user appealed, but the company again declined to act,

and only reversed course after the board took up the case, it

said.

In the American celebrity's case, Meta's systems

automatically removed the image.

"Restrictions on this content are legitimate," the board

said. "Given the severity of harms, removing the content is the

only effective way to protect the people impacted."

The board recommended Meta update its rule to clarify its

scope, saying, for example, that use of the word "photoshop" is

"too narrow" and the prohibition should cover a broad range of

editing techniques, including generative AI.

The board also slammed Meta for declining to add the Indian

woman's image to a database that enables automatic removals like

the one that occurred in the American woman's case.

According to the report, Meta told the board it relies on

media coverage to determine when to add images to the database,

a practice the board called "worrying."

"Many victims of deepfake intimate images are not in the

public eye and are forced to either accept the spread of their

non-consensual depictions or search for and report every

instance," the board said.
