You're scrolling TikTok. A distinguished professor appears — gray hair, authoritative voice, Liverpool University credentials. He's recommending a probiotic for menopause symptoms. Nearly 400,000 views. Thousands of bookmarks. Comments thanking him for the advice.
Here's the problem: that professor is real. His expertise is real. But that video? Every single word was fabricated by artificial intelligence. And he's just one victim in an epidemic of deepfaked academics selling you supplements with endorsements they never gave.
The Professor Who Never Spoke
Professor David Taylor-Robinson is a public health expert at the University of Liverpool. His research focuses on child poverty, health inequalities, and early childhood development. Menopause? Not his field. Not even close. He's never discussed it professionally.
Yet in early 2025, fourteen TikTok videos appeared featuring his face, his voice, his credentials — all recommending probiotics for menopausal symptoms. Full Fact, Britain's independent fact-checking organization, discovered these videos had accumulated over 365,000 views, nearly 8,000 likes, and 2,878 bookmarks from people saving this fake medical advice for later reference.
The videos promoted Wellness Nest probiotics. But here's the twist — when Full Fact contacted the company, they said the content was "100% unaffiliated" with their business. The scammers weren't even working with the supplement company. They just picked a product, stole a professor's identity, and started printing misinformation.
And Taylor-Robinson wasn't alone. Full Fact also found eight deepfake videos impersonating Duncan Selbie, the former chief executive of Public Health England, using manipulated footage from a 2017 public health event.
'Thermometer Leg' and the Art of Invented Diseases
Ever heard of "thermometer leg"? Neither has any doctor — because it doesn't exist.
The deepfake videos promoted cures for a condition where menopausal women supposedly extend one leg from blankets when feeling hot. Sounds almost plausible, right? That's the trick. They named a normal human behavior — something anyone might do — then pathologized it. Turned it into a condition you need to treat.
It's a classic manipulation technique: create the problem, then sell the solution. Except in this case, both the problem and the expert recommending the solution were completely fabricated.
This scam exploits something psychologists call authority transfer. We trust experts. We trust credentials. When someone with "Professor" in their title gives advice, we listen differently. That trust is hardwired — it evolved because listening to experts kept us alive. Now it's being weaponized by people who understand the psychology better than we do.
Six Weeks to Remove Fourteen Lies
When Professor Taylor-Robinson discovered these videos, he reported them to TikTok. Their response? Some videos were removed. Others were deemed acceptable.
Six weeks. That's how long it took to get all fourteen deepfake videos removed from the platform. Six weeks of fake medical advice reaching hundreds of thousands of viewers.
Taylor-Robinson described the removal process as "a faff" — inconsistent enforcement, mixed messages, no clear path to protecting your own identity. And this is TikTok's own policy we're talking about. They explicitly prohibit impersonation. They have rules against health misinformation. The deepfakes violated both.
But social media platforms are drowning in content. Billions of videos uploaded daily. AI-generated content is becoming indistinguishable from real footage. The Full Fact investigation found an entire infrastructure of fake academic endorsements operating across platforms — some accounts posting multiple deepfakes per day. Different professors, different products, different made-up conditions. It's industrialized fraud.
The Economics of Digital Puppetry
Think about the math. If one deepfake video gets 365,000 views before removal and converts even a fraction to sales, that's potentially thousands of orders. Then you make another video. By the time platforms catch up, the scammers have moved on. New accounts. New professors to impersonate. New conditions to invent.
The wellness supplement industry is worth billions and operates in a regulatory gray zone. Unlike pharmaceutical drugs, supplements don't require clinical proof of effectiveness before hitting the market. That creates a perfect storm: products that need marketing but can't make specific medical claims legally. Enter the deepfaked professor with borrowed credibility.
Avast, the cybersecurity company, reported that AI is fueling a surge in TikTok scams, with health products among the most common targets because margins are high and enforcement is slow. Media Matters found similar patterns — AI-generated influencers and deepfaked experts selling everything from weight loss supplements to immune boosters to anti-aging products.
The playbook never changes: borrow someone's credibility, invent a problem, offer a solution, disappear before anyone notices.
How to Spot a Fake Professor
The technology isn't going away. It's getting better. And the people misusing it are learning faster than platforms can adapt. So here's your survival kit:
Verify the expertise. A children's health expert discussing menopause? That's a red flag. Check if the person actually works in that field.
Search for the condition. If you can't find it in legitimate medical literature, it might not exist. "Thermometer leg" returns no results in medical databases — because it's not real.
Follow the money. Be suspicious of any health advice that leads directly to a product purchase. Real medical guidance points you toward doctors, not shopping carts.
Check for official accounts. Real professors usually have university profiles or verified accounts. If you can't find them outside the product pitch, that's telling.
Watch the mouth. Look for lip-sync issues, unnatural speech patterns, video quality inconsistencies. Deepfakes are good but not perfect. The mouth movements often lag slightly behind the audio.
The irony here is painful. These deepfakes work because people actually want expert guidance. They're seeking authoritative information. And scammers are meeting that need with lies dressed in stolen credentials.
Digital literacy isn't optional anymore — it's survival equipment. The ability to verify, question, and fact-check is now a core life skill. Teach it to the people in your life. And when you see something suspicious, don't just scroll past. Report it. Be the fact-checker your corner of the internet needs.
The fake professors aren't going away. But neither are the people asking questions.
