Social media metrics can play an important role in litigation, but follower counts and engagement numbers don’t always tell the full story. Social media expert Kate Talbot's recent article that explains how experts can evaluate fake followers, identify suspicious audience patterns, and assess the credibility of an online following.
I was laughing the other day with my friend about how we'll check out an Instagram account that has millions of followers, but we both have no idea who this person is.
They're not a celebrity. They're not even someone either of us has ever heard of. So the obvious question becomes: How did this account end up with millions of followers?
While we're scrolling through their content and follower list to understand how they've made it big (or not!), it reminded me of the cases that I've worked on as as a social media expert witness.
When I get pulled into a case surrounding follower count, which usually involves influence, value, or damages, the number on the profile almost never tells the real story.
Who Are These Followers?
I wanted to dive deeper into this from a social media expert witness perspective and I found a case from 2019. New York's Attorney General settled with a company called Devumi that had sold more than 200 million fake Twitter followers, and called it what it was: illegal deception.
"The FTC has since banned buying fake followers to fake influence, with real financial penalties attached, and has started sending warning letters. As regulators and courts look harder at creator content, the distance between how big an account looks and how big it really is becomes something you have to prove, not assume."
A follower count is not a fact. It is a claim, and it is testable.
Why Follower Count Does Not Measure Real Audience Value
Followers are the easiest social media metric to inflate. You can buy them or they accumulate on their own from bots and dead accounts. An account can show a million followers and have almost no real audience behind it.
There have been countless news stories about influencers selling merchandise and having such low sales, because their followers are inflated.
The number that matters is engagement, and this is where value lives. It is a lot harder to fake.
How a Social Media Expert Witness Evaluates Audience Authenticity
Depending on the case, I use platform analytics, historical data, and third-party tools like Social Blade and Modash to evaluate whether an audience appears authentic.
1. Social Blade gives me the public history. Follower growth over time, engagement patterns, and the shape of the account's activity. Bought audiences show a strong pattern. You often see a sharp spike in followers on a specific date, then a flat stretch where nothing grows organically. Real accounts do not usually move like that.
2. Modash goes deeper on audience quality. It scores the share of followers that look fake or inactive, flags red flags like missing profile details and suspicious follower-to-following ratios, and lets me compare the engagement rate against what is normal for an account that size. As a rough anchor, an engagement rate in the 1 to 3 percent range is ordinary. An account with a million followers and engagement well under that has an audience quality problem worth explaining to a court.
The comments tell you a lot too. Bot engagement is repetitive and generic. Real audiences argue, ask questions, tag friends, and go off topic. You can see the difference by reading.
Why this matters for damages
If an endorsement deal, a licensing claim, or a reputational harm number is pegged to apparent reach, and the real reach is a fraction of the apparent reach, the damages figure is built on sand.
Apparent influence and actual influence can differ by an order of magnitude. An account that looks like it reaches a million people might genuinely reach a few thousand. That gap is not a rounding error in a valuation. It can be the difference between the two sides' numbers.
The same analysis runs in reverse in a defamation matter. When the claim is that a post did serious reputational damage, the real questions are how far it actually traveled and how many real people saw it. An impressive follower count on the account that posted it does not answer that. The engagement data starts to.
Where this is going
The gap between apparent and real influence is getting wider, not narrower. Bought audiences are cheap. AI-generated engagement is getting better. The follower count on a profile is going to keep drifting further from the real reach behind it.
Courts are going to need people who can tell the difference and show their work. That is the part of this I find most interesting, and it is where a lot of my work is headed.
