Affiliate fraud is any attempt to earn commissions for actions that were never genuinely generated: fake clicks, fake leads, hijacked attribution or users who never meant to convert. In mobile and MVAS, where payouts are fixed per action and users pay through their carrier, fraud does not only cost the advertiser money. It triggers carrier complaints, blocks services in whole countries and gets honest affiliates' conversions scrubbed along with the bad ones.
This guide covers the common affiliate fraud tactics in mobile performance marketing, the warning signs in your data, and how advertisers, networks and affiliates can prevent affiliate fraud. It is written by Mobipium, a mobile affiliate network that has filtered traffic on MVAS and dating offers since 2013.
What Is Affiliate Fraud?
Affiliate marketing fraud happens when a partner, or someone pretending to be one, manipulates traffic, leads or attribution to collect commissions. It can be done by an affiliate, by a traffic source that sells fake traffic to an affiliate, or by automated systems that imitate real user behavior.
The outcome is always the same: the advertiser pays for value it never received. In response, advertisers scrub conversions, cut payouts and close offers, which hurts every affiliate on the program, not just the fraudsters.
Why Mobile and MVAS Are a Target
- Fixed payouts per action. CPA and CPL offers pay a known amount for each conversion, which is easy to target with fake actions. We explain each model in CPA vs CPL vs CPS vs RevShare.
- Short funnels. A one-click carrier-billed subscription has fewer steps to verify than a card checkout.
- Huge, cheap traffic. Pop, push and in-app inventory includes bots and low-quality placements mixed with real users.
- Regulated billing. Every subscription is charged on a real person's phone bill. If that person did not mean to subscribe, the complaint goes to the carrier and the regulator. See how carrier billing works.
Common Affiliate Fraud Tactics in Affiliate Programs
| Tactic | How it works | Where it shows up |
|---|---|---|
| Bot traffic | Automated systems generate fake clicks and sometimes fake conversions | Pop, push, native, cheap in-app inventory |
| Click farms | Real devices operated by paid workers fake engagement and sign ups | CPL and app install offers |
| Click injection and click spamming | Malicious apps fire a click just before an install to steal attribution | Android app install campaigns |
| Fake leads | Forms filled with stolen or invented data | Dating SOI, sweepstakes, lead generation |
| Misleading or forced subscriptions | Landers hide the price or trick users into confirming a subscription | MVAS one-click and pin-submit flows |
| Incentivized traffic in disguise | Users are paid or rewarded to convert, on offers that ban incentives | Any CPA or CPL offer |
| Geo and device spoofing | Proxies and emulators fake a high-paying GEO or device | Tier 1 offers with high payouts |
| Cookie stuffing | Hidden cookies claim credit for sales the affiliate did not drive | Web CPS and e-commerce programs |
| Brand bidding | Affiliates bid on the advertiser's brand keywords in Google Ads to intercept existing customers | Search-based CPS and CPA programs |
The MVAS-specific risk: subscriptions the user did not understand
In MVAS the most damaging fraud is not always a bot. It is a real user who subscribed without understanding it: a lander with a hidden price, a fake "download" button that triggers a one-click subscription, or a pre-lander that impersonates a system alert. These subscriptions convert, so they look great in the first hours. Then the complaints arrive, the carrier refunds users, the advertiser loses its billing connection and the whole GEO can close for everyone.
That is why compliance is part of fraud prevention in this vertical. We explain how each flow handles consent in Mobile Billing Flows Explained.
The Real Cost of Affiliate Fraud
Fraudulent activity costs more than the commissions paid for fake actions. Advertisers lose ad spend and revenue, but they also lose clean data: once fake leads and bot traffic enter the numbers, every optimisation decision is made on the wrong signal. In MVAS there is a third cost. Carriers measure complaint rates per service, and a few days of forced subscriptions can cost an advertiser a billing connection that took months to build. That is why many advertisers treat a network's fraud protection as part of the price, not an extra.
For affiliates, the cost is scrubbed conversions and lost access. When an advertiser finds fraud in a network's traffic, it often cuts payouts for every partner on that offer. Honest affiliates pay for someone else's scam.
Fraud Detection: Warning Signs in Your Affiliate Traffic
| Signal | What it may mean |
|---|---|
| Thousands of clicks with zero conversions from one placement | Bot traffic or a broken placement |
| Conversion rate far above the GEO average overnight | Fake leads, forced subscriptions or incentivized traffic |
| Conversions seconds after the click, every time | Automated systems or click injection |
| Many conversions from the same IP addresses or device models | Click farms or emulators |
| Clicks from a GEO that does not match the carrier | Proxy or geo spoofing |
| Strong day-one numbers, then high refunds or early cancellations | Users who did not mean to subscribe |
| High bounce rates with no engagement on the advertiser side | Non-human or uninterested traffic |
One signal alone proves nothing. Real user behavior is messy, and a single viral placement can look suspicious. Fraud detection works when several signals line up on the same source.
Affiliate Fraud Outside Mobile: Cookie Stuffing, Coupon Codes and Brand Bidding
Most articles about affiliate fraud are written for e-commerce brands, so they focus on three web tactics. Cookie stuffing drops affiliate cookies on users who never clicked, so the affiliate claims sales from other channels. Coupon code leaks happen when exclusive affiliate coupons end up on coupon websites and collect commission on sales that would have happened anyway. Brand bidding means affiliates buy the brand's own keywords in Google Ads and intercept customers who were already searching for the brand.
These tactics matter for CPS programs on websites. In mobile CPA and MVAS, where the payout is tied to a carrier-billed subscription or an install, the bigger risks are bots, click injection, fake leads and misleading subscription flows. Identify which model you run before you choose your fraud strategy and tools.
How to Prevent Affiliate Fraud: What Networks Do
A network sits between the traffic and the advertiser, so it is the natural place to filter. Here is what serious networks do, with how Mobipium handles each one:
1. Know who they pay
Payments require identification. Mobipium pays only after a signed IO and either a certificate of tax residence for companies or an ID document for individuals. Anonymous accounts are where fraudsters hide.
2. Filter clicks before they reach the offer
Clicks that do not match the offer's GEO, device, carrier or time frame are blocked, and placements that send a high number of clicks without conversions can be capped automatically. Mobipium's stage report shows every blocked click by reason: targeting block, offer status block, leads cap block, time frame block, clicks cap block and PubID block.
3. Block bad sources at the placement level
Instead of banning a whole affiliate for one bad source, networks block specific sub-IDs or placements. That protects honest affiliates who bought a bad placement by mistake.
4. Test offers and landers in-house
Every Mobipium offer is tested by our internal media buying team before affiliates see it, and the pre-landers in the campaign setup have already run on real traffic. A network that knows what normal performance looks like for an offer spots abnormal performance faster.
5. Monitor in near real time
Fraud is cheap to stop early and expensive to stop late. Stats that update every 15 minutes make it possible to react within the same day instead of after the invoice.
How Affiliates Protect Their Traffic Quality
- Buy from reputable traffic sources and check their own fraud protection before you scale.
- Pass sub-IDs on every click so you and your network can cut bad placements, not whole campaigns.
- Use the network's compliant landers or get yours approved. Never hide the price or the subscription terms.
- Watch quality, not only volume. If a source suddenly converts three times better than the rest, check it before you raise bids.
- Talk to your account manager when something looks off. A network sees patterns across all its partners that you cannot see alone.
What Advertisers Should Ask an Affiliate Network
- How do you verify affiliates before you pay them?
- Can you block traffic at the placement level, not just the affiliate level?
- How fast do you see and act on abnormal conversion rates?
- Who tests the offers and landers before they go live?
- How do you handle compliance for carrier-billed flows in each GEO?
