‘Daisy v Scammers’ by VCCP won gold in Advertising Use of GenAI at The Drum Awards. This campaign built an AI system sophisticated enough to fool professional scammers, generating authentic content for a campaign while preventing fraud in real-time. The AI system, Daisy, engaged scammers, wasting their time and creating viral content, proving AI's potential for both utility and creativity.
Seven in ten Brits were targeted by scammers last year, with criminals impersonating telcos like O2, destroying customer trust and damaging our industry's reputation. One 78-year-old victim told us: 'My phone has become a device of horror and dread.' We set ourselves an audacious technical and creative challenge: Could we build an AI system sophisticated enough to fool professional scammers? Not to make ads about fraud prevention, but to actually prevent fraud in real-time while simultaneously generating authentic content for a campaign.
Dual Innovation: Story Doing AND Story Telling
Our breakthrough insight combined cutting-edge generative AI technologies into one unified system that would operate on two revolutionary levels. First, the 'story doing' – actually wasting scammers' time at scale through functional innovation. Second, the 'storytelling' – transforming those real interactions into viral content through creative innovation.
This wasn't using AI to produce a campaign. This was building an AI system that would BE the campaign – gathering its own content through genuine interactions with criminals to feature in PR and social media comms.
Strategic Objectives
We aimed to build a complete AI system, combining multiple technologies into one seamless experience that could achieve human-level authenticity, fooling professional criminals. The system would then capture content from real scammer interactions, ready to be used by Daisy, brought to life as a virtual influencer, and demonstrate GenAI's potential for both utility and creativity simultaneously.
Introducing The Granny Who Never Sleeps

Meet Daisy – a chatty granny with all the time in the world. She loves talking about her cat Fluffy (whose adventures change with every call), has strong opinions about the proper way to make lemon meringue pie, and can spend twenty minutes describing her latest knitting pattern before remembering why you called.
But Daisy isn't just charming – she's revolutionary. She represents a new model for generative AI in advertising: both weapon and content creator, a technical marvel that fights crime while documenting her feats of frustration, for the world to enjoy.
Execution
Building the AI System
Creating Daisy required orchestrating an entire ecosystem of AI technologies working in perfect harmony. We integrated Deepgram's speech recognition for real-time voice transcription with GPT-4 Mini, which we custom-trained on scambaiter Jim Browning's data to recognize and respond to scam-specific tactics. We also developed Daisy’s personality profile. This step in world-building was crucial to give Daisy enough depth that she came across as ‘real’. The team contributed many memories of their own grannies, which informed Daisy’s backstory from baking to playing bridge. This gave her the means to go on endless tangents to frustrate scammers.
Another key ingredient was her voice. We used a custom-trained voice in ElevenLabs to synthesize the voice of a real colleague's grandmother to capture those authentic British inflections, the slight breathlessness, the way she says 'oh dear' when confused.
For her visual identity, we used Flux and ComfyUI to virtually cast the perfect grandmother you'd help with her shopping, then brought her to life through Kling AI with perfect lip-sync for video content. Every element was designed to create conversations indistinguishable from a real person. An elderly person was also perfect in other ways. Driving down latency was a huge challenge. Even with careful selection of components that reduced it to a couple of hundred milliseconds, playing into the unconscious bias scammers have of the elderly helped mitigate occasional lag in the system.
The Story Doing Revolution
Daisy doesn't just exist; she performs. She answers scammer calls and improvises in unique conversations with each criminal. She remembers previous interactions during long conversations. She’s wasted up to 40 minutes of scammers' time on a single call, with stories about the birds in her garden or how to prune roses, and can do this while operating in parallel with multiple, concurrent conversations.
This wasn't a simulation; it was real-time crime prevention through AI. Every minute Daisy chatted about her grandchildren was a minute a scammer couldn't spend targeting real victims.
From Functional Tool to Content Goldmine
The best part about Daisy is that every scammer interaction became potential content. In essence, scammers wrote the scripts for us through their genuine frustration ('Stop calling me dear, you stupid ****!') and dramatic reveals when scammers realized they'd been played.
We built a content generation loop that fed itself: the AI system engages scammers, conversations generate authentic moments, the best content becomes social media posts, viral spread attracts more people sharing scammer numbers, meaning more scammers calling Daisy, creating more content.

Creating a Virtual Influencer
Daisy evolved from a functional tool to a beloved personality. We developed her into a full virtual influencer with hero content featuring shocking scammer recordings, best moments for social clips, and rich character development through her stories about her cat, Fluffy, her Tuesday knitting club, and that secret lemon meringue recipe she'll share if you just listen a bit longer.
We crafted a multi-platform presence with YouTube long-form conversations, TikTok clips of scammer meltdowns, and Instagram reels of Daisy's best comebacks. We even produced a Christmas special, complete with AI-generated visuals of Daisy and Fluffy by the fireplace, to warn viewers that scammers don’t take holidays.
Technical and Creative Excellence
The system worked because the field of Gen-AI evolves so rapidly. We pivoted to integrate new models and tools that hadn’t existed at the beginning of the process. We obsessed about latency optimization so responses felt natural, and weaponized scammers' unconscious bias towards the elderly to mitigate the occasional lag. We built personality depth through complete world-building that made her believable, from the way she mishears things ('playstore' as 'pastries') to how she gets progressively more flustered when rushed.
Voice authenticity came from capturing every nuance: conversation tone, regional accent, breathing patterns, and the little 'hmm' sounds while thinking. The system showed contextual awareness, adapting to different scam types, and an emotional range from confused to indignant to delightfully chatty.
We maintained responsible innovation throughout: transparent about AI use to everyone except scammers, targeting only verified scammer numbers, and built-in safeguards against misuse.
