Why attorneys retain her
Defamation cases on social media require understanding not just what was said, but how widely it spread and through what mechanism. Kate Talbot's platform expertise means she can explain why a defamatory post reached millions through algorithmic amplification rather than organic sharing — and why that distinction matters for damages. She can also analyze whether engagement was authentic or artificially inflated, which affects the scope of actual harm.

Frequently asked questions
What does a social media expert witness do in a defamation case?
A social media expert witness analyzes how defamatory content spread, how many people were exposed to it, what platform mechanics drove its distribution, and what the data shows about reputational impact. Expert testimony helps courts understand the scope of publication and the mechanics of online harm.
How is reach measured in a social media defamation case?
Reach analysis requires platform-native data — not screenshots of impression counts. Relevant metrics include organic reach, algorithmically amplified reach, reshare and repost distribution, geographic distribution, and audience demographics. Expert analysis distinguishes between passive exposure and meaningful engagement.
Does algorithmic amplification affect defamation damages?
Yes. When a defamatory post reaches millions of people through platform algorithmic amplification rather than organic sharing, the scope of publication — and potentially damages — is significantly larger than the original poster intended or caused. Expert testimony is required to explain this distinction to courts.
When should a social media expert witness be retained in a defamation case?
As early as possible. Viral content often disappears or ages out of platform retention windows quickly. Early retention allows for proper preservation of platform data and ensures the most complete record of how the content spread.
