It’s not just you. More weird spam is popping up on Facebook

Clare Duffy, CNN

New York (CNN) — If a unusual photograph has precocious stopped you successful your tracks while scrolling your Facebook feed, you’re not alone.

Users who erstwhile came to Facebook to link pinch friends and family are progressively complaining of random, spammy, junk contented — overmuch of it apparently generated by artificial intelligence — showing up successful their feeds.

Sometimes it’s evidently fake, AI-generated images, for illustration nan now-infamous “Shrimp Jesus.” Other times, it’s aged posts from existent creators that look for illustration they’re being reshared by bot accounts for engagement. In immoderate cases, it’s pages sharing streams of seemingly benign but random contented — memes aliases movie clips, shared each fewer hours.

But nan spam is much than conscionable an annoyance; it tin besides beryllium weaponized. Some spam pages look designed to scam different users. In utmost cases, spam pages that summation a pursuing tin yet beryllium used, for example, by overseas actors seeking to sow discord up of elections, according to experts who study inauthentic behaviour online.

The surge coincides pinch an intentional strategy displacement astatine Facebook successful nan past fewer years. The institution de-emphasized existent events and authorities successful nan aftermath of claims it had contributed to predetermination manipulation and real-world violence. Feeling nan power from nan emergence of TikTok and its accent connected intermezo complete societal connections, Facebook re-designed users’ location feeds into a “discovery engine” successful nan hopes that group would prosecute pinch contented they mightiness not different see.

But nan push for much “discoverable” contented has led to an algorithm that regularly pushes vapid, often misleading, computer-generated content.

The alteration has been palpable. AI-generated aliases recycled meme contented has appeared connected Facebook’s quarterly astir viewed contented list. Posts pinch evidently AI-generated images and confusing captions sometimes person thousands of likes and hundreds of comments and shares.

Bad actors and engagement farmers are only excessively happy to fulfill Facebook’s request for caller content, experts say. And nan proliferation of AI devices has made it acold easier for them to quickly crank retired immense volumes of clone images and text.

“It’s a really absorbing point that a batch much group are starting to talk astir because it’s this random, benignant of vanilla problem now, but evidently location are theoretical, semipermanent concerns,” said Ben Decker, CEO of online threat study patient Memetica.

Facebook genitor institution Meta, for its part, useful “to region and trim nan dispersed of spammy contented to guarantee a affirmative personification experience, offering users controls complete their provender and encouraging creators to usage AI devices to nutrient high-quality contented that meets our Community Standards,” spokesperson Erin Logan said successful a statement. “We besides return action against those who effort to manipulate postulation done inauthentic engagement, sloppy of whether they usage AI aliases not.”

Adventures successful nan AI swamp

Before I started reporting this communicative successful July, my Facebook provender felt beautiful normal, featuring babe photos from assemblage friends and listings from Facebook Marketplace.

But, funny astir nan complaints, I started clicking connected immoderate contented I did spot that seemed odd, and nan algorithm kicked in. Now, weeks later, astir each 3rd station connected my provender appears to beryllium alleged “AI slop.”

One caller example: a black-and-white image showing a shack successful nan woods pinch a family sitting retired front, shared by a page called “History for Everyone.”

At first glance, nan station looks for illustration thing you mightiness find successful a history book. But upon person inspection, nan group successful nan image person blurred, undefined facial features, and nan children’s hands and feet look to vanish into nan scenery astir them — hallmarks of AI-generated images.

The post’s caption claims nan image was taken successful 1910 successful New Jersey astatine a “small shack connected Forsythe’s Bog, occupied by De Marco family, 10 successful nan family surviving successful this 1 room,” by National Child Labor Committee photographer Lewis Hine. Curious, I copied nan afloat caption into Google, which pointed maine to nan existent caption of an wholly different photograph that had been published by nan Library of Congress.

I plugged nan Facebook image into a Google reverse image search, and nan only different places it appeared online were 2 other, akin Facebook groups called “Past Memories” and “History Pictures.”

It’s intolerable to opportunity definitively really nan image was created, but CNN’s photograph squad ran it done AI-detection package — which is still successful early testing — and recovered “substantial evidence” it had been manipulated. Hany Farid, a integer forensics master and UC Berkeley professor who has studied AI, added that nan image appeared to beryllium AI-generated and whitethorn person been created by utilizing nan caption of nan real, humanities image arsenic nan AI prompt, perchance to debar copyright infringement.

The group that shared nan post, “History for Everyone,” is managed by a page by nan aforesaid name, which was created successful 2022 and antecedently changed its sanction from “Cubs” and “Chikn.Nuggit.” The page did not respond to a nonstop message.

The History for Everyone station is schematic of a batch of nan contented that’s travel crossed my provender — uncanny, bizarre, but besides seemingly benign.

Other examples see a page called “Amy Couch” that besides shares “historical” photos, pinch an apparently AI-generated floor plan photograph that shows a female pinch 1 elephantine bony wherever her 2 beforehand teeth should be. Or an creation and history page for an “artist” called “Kris Artist” whose floor plan photograph I traced backmost to a existent societal media influencer who told maine complete email: “That is decidedly not my relationship but they are utilizing my picture.”

When I messaged nan “Kris Artist” page, I received what appeared to beryllium an automated response: “Hi, acknowledgment for contacting us. We’ve received your connection and admit you reaching out. Please Join our Group.”

After I flagged nan History for Everyone post, arsenic good arsenic nan Amy Couch and Kris Artist pages, to Meta, it removed them for violating its spam policy.

Behind nan AI slop

It’s not clear precisely really overmuch of this contented exists connected Facebook. But location whitethorn beryllium tons of group seeing it. The “History for Everyone” page has much than 40,000 followers, though individual posts often person conscionable a fistful of interactions.

Researchers from Stanford and Georgetown earlier this twelvemonth tracked 120 Facebook pages that often posted AI-generated images — and recovered nan images collectively received “hundreds of millions of engagements and exposures,” according to a insubstantial released successful March, which has not yet been peer-reviewed.

“The Facebook Feed … astatine times shows users AI-generated images moreover erstwhile they do not travel nan Pages posting those images. We fishy that AI-generated images look connected users’ Feeds because nan Facebook Feed ranking algorithm promotes contented that is apt to make engagement,” researchers Renee DiResta and Josh Goldstein wrote successful nan paper. They added that often nan users engaging pinch that contented didn’t look to recognize it was AI.

Experts who way this benignant of online behaviour opportunity location are apt respective different kinds of actors down nan Facebook spam, pinch varying motives.

Some conscionable want to make money, for illustration done prize payments that Facebook pays retired to creators posting nationalist content. There are dozens of YouTube videos school group really to get paid for posting AI contented connected Facebook — arsenic tech news tract 404 Media reported earlier this period — pinch immoderate claiming they make thousands of dollars each period utilizing nan tactic.

“Even successful nan realm of nan political, nan strategies of manipulators person agelong been previewed by those pinch a different motivation: making money. Spammers and scammers are often early adopters of caller technologies,” nan Stanford researchers wrote.

On different pages, scammers usage nan comments arsenic a spot to hawk sham products aliases cod users’ individual information.

In immoderate cases, what looks for illustration a harmless relationship sharing mostly random contented will gaffe successful occasional misinformation aliases violative memes, arsenic a measurement of evading Facebook’s enforcement mechanisms. “If thing looks conscionable for illustration a run-of-the-mill spam campaign, it mightiness not trigger nan company’s apical investigators … and truthful it mightiness spell undetected for longer,” said David Evan Harris, an AI interrogator who antecedently worked connected responsible AI astatine Meta.

Harris added that location is besides an online marketplace for “aged” Facebook accounts, because older accounts are much apt to look quality and evade nan platform’s spam filters.

“It’s for illustration a achromatic market, basically, you tin waste personification 1,000 of these accounts that are each 5 years aliases older, and past they tin move those into a scam aliases an power operation,” Harris said. “This is thing you spot successful elections: Someone mightiness make a Facebook group that’s like, ‘everybody loves cheeseburgers,’ and nan group posts images of nan champion cheeseburgers each time for 2 years, and past each of a sudden, a period earlier an predetermination … it becomes a ‘vote for (former Brazilian President Jair) Bolsonaro’ group.”

What to do pinch AI spam?

With AI tools, bad actors nary longer request tons of group to quickly nutrient reams of clone contented — nan exertion tin do it for them.

For Facebook to place each of nan AI-generated images getting uploaded each time without making mistakes would beryllium challenging, “particularly astatine a clip erstwhile this exertion is moving truthful incredibly fast,” Farid said. Even if it could, “that doesn’t mean you should prohibition each AI generated content, right? … It’s a very subtle mobility connected policy,” he said.

Earlier this year, Meta said it would adhd “AI info” tags to contented created by definite third-party generators that usage metadata to fto different sites cognize AI was involved. Meta besides automatically labels AI-generated images created pinch its ain tools.

However, location are still ways for users to portion retired that metadata (or create AI images without it) to evade detection.

Meta whitethorn besides beryllium hampered by a smaller squad dedicated to addressing clone content, aft it — for illustration different tech giants — trimmed its spot and information unit past year, meaning it must trust much connected automated moderation systems that tin beryllium gamed.

“Digitally savvy societal media communities person ever been 1 and a half steps up of spot and information efforts astatine each platforms … it’s almost a feline and rodent crippled that ne'er really ends,” Harris said.
