Social Media Is Fueling Illegal Wildlife Trade—Why Deleting Posts Won’t Stop It

Social media has made illegal wildlife trade easier to advertise, scale and conceal. Public posts and videos can attract buyers, while direct messages and private channels help sellers negotiate payments and delivery. A six-week monitoring effort in the United States found more than 1,600 primates advertised across Facebook, Instagram, TikTok and YouTube during mid-2025.

That finding sits within a broader warning from biodiversity researchers: online platforms are not simply passive noticeboards for wildlife sales. They can form part of the infrastructure that connects sellers, buyers, payment systems and physical transport across borders. 16

What researchers documented

The primate figure comes from a report focused on the U.S. market. Researchers identified listings across four major platforms, sometimes presenting animals as available for “rehoming” or “adoption.”

The wider online trade extends well beyond primates. Reports and research describe advertising involving birds, snakes, frogs, orchids and other plants, as well as animal parts and products made from protected species.

Sellers may use ordinary photographs and videos, coded terms, public posts and contact details to reach potential customers. Conversations can then move into direct messages or more private and encrypted services, where arrangements are harder for researchers and platforms to observe. Earlier research has identified social media as a particularly difficult venue to monitor because of its large user base and high volume of content. 6

Why online trafficking networks expand

Digital platforms lower the barriers to reaching customers. A seller can publish to a large audience without maintaining a visible physical stall, and pseudonymous or disposable accounts can make identities harder to establish. If an account or listing disappears, a replacement can be created quickly.

Online activity also complements rather than eliminates physical smuggling. Animals and wildlife products still have to be stored, transported and delivered, but digital tools can make it easier to coordinate those steps and communicate with overseas buyers. The result is a trade that can move between public platforms and private channels instead of following one easily identifiable route. 16

The scale of online content creates an enforcement problem of its own. Manual review cannot reliably examine every image, video, caption and message, while species names may be missing, deliberately altered or embedded only in photographs. Research on online wildlife markets has therefore pointed to machine learning as a way to identify suspicious material at high volume, provided that automated flags are checked by trained reviewers. 67

Cambodia’s warning shows the legal and social stakes

Cambodia’s Ministry of Environment called on social-media users and content creators to stop posting material that sells, promotes, consumes or captures protected wildlife. The ministry said some people were using rare animals and plants to attract attention and generate clicks, while others were using social media to trade them.

The ministry also warned that wildlife offences can carry prison sentences of five to 10 years. Cambodia does not have a separate law specifically dedicated to online wildlife trading, but the ministry said advertising, selling, ordering or transporting wildlife and wildlife specimens by any means can constitute an offence.

The warning reflects a central challenge: visible content is only the most accessible part of a larger market. A post may be made by a reseller rather than the supplier, and a public listing may lead to negotiations elsewhere.

Operation Sandokan points to a wider criminal ecosystem

A separate Earth League International investigation, Operation SANDOKAN, examined wildlife-trafficking networks in Cambodia and the Lower Mekong region over more than a year. The investigation focused on hubs including Phnom Penh, Sihanoukville and Bavet and alleged links between wildlife trafficking, scam compounds, corruption and other transnational crimes.

The report described products including tiger parts, rhino horn, ivory and pangolin scales, and documented the use of digital communication channels including WeChat and Telegram. These findings are investigative allegations by Earth League International, not judicial findings or proof that every user of those platforms is involved in trafficking.

The significance of the investigation is its focus on networks rather than isolated advertisements. Wildlife trafficking can involve suppliers, brokers, storage facilities, transporters, financiers, corrupt facilitators and end buyers. Conservation efforts that focus only on removing animal images may miss the people and infrastructure that keep the trade operating. A Nature commentary made a similar point, arguing that conservation action will have limited effect if it neglects the criminal systems that facilitate trafficking. 3

Why removing a listing is not enough

Deleting an advertisement can reduce its immediate visibility, but it does not necessarily remove:

• the seller’s other accounts;
• buyer and supplier contacts;
• payment or delivery arrangements;
• records that could support an investigation; or
• the physical networks that source and transport wildlife.

Traffickers can change wording, move customers to private messaging, maintain backup profiles and repost after a takedown. For that reason, effective enforcement needs to preserve digital evidence and connect online leads with financial, customs and physical-trade investigations. 16

This does not make moderation unimportant. It means moderation should be part of a wider disruption strategy rather than the entire response.

Five measures researchers recommend

1. Use AI-assisted monitoring with human review

Image, video, text and coded-language tools can help identify suspected listings across high-volume platforms. Human specialists remain necessary to verify species, interpret context and reduce false positives. 16

2. Require stronger, independently audited platform enforcement

Platforms should be assessed on more than the number of posts removed. Useful oversight would examine detection systems, repeat-offender action, evidence preservation, reporting transparency and response times. 1

3. Connect platform data to real investigations

Wildlife authorities, police, customs agencies, financial investigators, conservation groups and local communities need channels for sharing intelligence. A suspicious listing is most valuable when it can help identify a supplier, payment trail, shipment or organized network. 13

4. Reduce demand

Public campaigns should address the reasons people buy wildlife—as pets, status products or purported medicinal goods—while supporting culturally informed and community-based alternatives. Removing supply-side listings without addressing demand risks leaving the market intact. 1

5. Strengthen international cooperation and rules

Cross-border information sharing and implementation of frameworks such as CITES are essential because online sales can connect buyers and sellers in different countries. Researchers also point to platform-accountability measures, including the EU Digital Services Act, as tools that could be adapted to wildlife-trafficking risks. 1

The central lesson

Online wildlife trafficking is a technology-enabled social, economic and organized-crime problem. Platforms can help detect and remove illegal listings, but they cannot solve the trade alone.

The most durable response combines better monitoring with investigations into money, logistics and criminal leadership. Governments, platforms, regulators, conservation organizations and local communities each control part of that response. Treating the problem as nothing more than a stream of posts to delete risks leaving the underlying trafficking system untouched. 13
