A wave of AI-generated fake personas is being used to push cheap marketplace goods across social platforms. For brands, the danger is adjacency. Your carefully built campaign can end up running beside synthetic, deceptive content, and the platform's word that it is safe is no longer enough.
Your ad does not have to be the problem. It just has to run next to one.
There is a growing trade in AI-generated fake people. Synthetic personas, manufactured to look like real individuals, are being used to push cheap marketplace goods across social platforms. Some of it is crude. Some of it is convincing. All of it is designed to deceive.
For brands the immediate problem is not that you would make this content. It is that your advertising can end up sitting next to it. Programmatic and social buying place your ads against inventory you never hand-picked, and synthetic deceptive content is now part of that inventory pool. The platform tells you the environment is brand safe. That assurance is worth less every quarter.
Brand safety used to mean avoiding obvious categories. Violence, hate, adult content. The new version is harder. It means avoiding content that looks legitimate but is fabricated, at a scale and speed that human review cannot keep up with.
Why it matters
For Australian advertisers, adjacency is a trust issue with a direct line to the brand. A customer who sees your logo beside a deceptive synthetic post does not separate the two. The association sticks. The cheaper and more automated your buying, the less control you have over what your brand ends up beside.
This also raises the bar on your own authenticity. In a feed filling up with manufactured people, real, verifiable, human brand content becomes a genuine point of difference rather than a nice-to-have.

What to do about it
Tighten your inventory controls. Use exclusion lists, vetted placements and tighter category settings rather than trusting default brand-safe settings.
Demand transparency from your buying partners. If an agency or platform cannot tell you where your ads ran, that is the answer.
Favour environments you can verify. Owned channels, known publishers and curated placements beat cheap open-exchange reach when trust is on the line.
Lean into being visibly human. Real faces, real proof, real stories read as more credible the more synthetic the feed becomes.
The platforms will keep saying it is safe. Check for yourself, because your customer will not give you the benefit of the doubt.
