# Fraud Protection

> Enable self-referral and disposable-email blocking, deduplication, new-customer gating, and traffic-quality monitoring in Introw.

**Open in Introw:** [Affiliate campaigns](https://app.introw.io/campaigns)

## How it works

Fraud controls are configured per campaign. Click attribution is always signed, so referrals cannot
be forged. On top of that you can enable self-referral blocking, disposable-email blocking,
deduplication, and new-customer gating, all configured on the campaign's **Quality** tab. The
campaign's **Links** tab then surfaces traffic patterns per link so you can spot abuse and revoke
links if needed.

These controls run automatically as conversions arrive, filtering or flagging suspect activity
before it accrues commission.

## Prerequisites

* A campaign with tracking installed.
* Write access to campaigns.

## Settings & configuration

Fraud controls live on the campaign at [Affiliate campaigns](https://app.introw.io/campaigns).

### Self-referral blocking

Block conversions where the converter matches the referring partner, so partners cannot game their
own links.

### Disposable-email blocking

Reject conversions whose email uses a known disposable domain, filtering out throwaway signups.

### Deduplication

Count a customer only once so repeated conversions from the same person do not over-reward a partner.

### New-customer gating

Reward only conversions from genuinely new customers, checked against existing records.

### Traffic quality

Configure the protections on the campaign's **Quality** tab, then monitor traffic on the **Links** tab, which surfaces click and conversion patterns per link (accepted, declined, and failed counts) and flags links to **Review** so you can spot anomalies and revoke abusers.

## Limits & gotchas

<Warning>
  Fraud controls reduce abuse but do not eliminate the need for review. Disposable-email blocking depends on a known list of domains, so a brand new disposable domain may slip through until the list updates. New-customer gating depends on your existing records being complete.
</Warning>

## Troubleshooting

* **A legitimate conversion was blocked** - check whether the email matched a disposable domain or the customer already existed.
* **A self-referral got through** - confirm self-referral blocking is enabled on the campaign.
* **Quality looks suspicious** - review the link on the **Links** tab and revoke it if needed.
