The Rising Challenge of Influencer Fraud in
2025
Influencer fraud has become one of the biggest threats to digital marketing ROI.
Fake engagement and audience manipulation continue to cost brands millions each
year.
Key Statistics on Influencer Fraud
Before diving into APIs, it’s important to understand the scale of the problem:
Over 49% of Instagram influencers were found to have engaged in some level of
fraud.
Marketers lose an estimated $1.3 billion annually due to fake influencer
activities.
30% of influencer campaigns underperform because of misrepresented
audience demographics.
Why Fraud Persists
Influencer fraud persists because of:
The ease of purchasing fake followers and likes.
Lack of transparency in influencer analytics.
Manual vetting processes that are slow and prone to error.
APIs solve this challenge by delivering transparent, real-time, and verified data

3. that no screenshot or manual check can match.
Understanding Influencer Authenticity
Influencer authenticity is more than follower counts. It reflects whether an
influencer’s identity, audience, and engagement are genuine and aligned with
brand values.
Elements of Influencer Authenticity
To evaluate an influencer’s authenticity, brands must look at:
Audience demographics – Are followers from relevant geographies and age
groups?
Engagement quality – Are comments authentic conversations or bot-generated
spam?
Content alignment – Does the influencer consistently create content aligned
with their niche?
Brand partnerships history – Are they transparent about collaborations?
Without APIs, most of this evaluation remains surface-level. With APIs, brands can
dig deeper into social media data to confirm what’s real and what’s fabricated.
How APIs Detect Fraudulent Partnerships
APIs enable brands to access structured, verified, and compliant influencer data
directly from platforms like Instagram, TikTok, YouTube, and LinkedIn. This helps
detect fraud at multiple levels.
1. Audience Verification
APIs provide detailed Instagram, TikTok, or YouTube follower demographics.
Instead of relying on influencers’ self-reported data, brands can verify if an
influencer’s followers are authentic.
Real follower insights vs. bot-heavy profiles.
Audience location checks to ensure regional targeting accuracy.
Cross-platform comparisons to spot inconsistencies.

4. 2. Engagement Analysis
Fraudulent influencers often buy likes and comments. APIs flag suspicious
engagement by:
Detecting sudden spikes in engagement that don’t align with follower growth.
Identifying repetitive or generic comments common to bots.
Comparing engagement ratios with industry benchmarks.
3. Growth Pattern Monitoring
Authentic influencers grow steadily. Fraudulent influencers often show erratic
growth. APIs track:
Follower acquisition trends.
Unnatural spikes due to follower-purchasing services.
Retention rates of audiences over time.
4. Partnership Transparency
APIs help detect if influencers fail to disclose paid promotions. Social listening APIs
scan for brand mentions and match them against declared partnerships.
This ensures compliance with advertising guidelines and prevents reputational
risks.

performance, and audience sentiment.

Identify sentiment shifts in influencer content.
Monitor engagement quality over time.
Detect controversial or risky content before partnerships.
APIs like Phyllo’s Social Media Intelligence help maintain continuous oversight,

reputation.
