Contact harvesting and coerced referrals

Contact harvesting and coerced referrals is a working label for this design mechanism: The service extracts contact information, sends or prepares unwanted invitations, or ties functionality to recruiting other people. This is editorial implementation guidance for Australian journeys, not a finding of unlawfulness. From 1 July 2027, a similar interface is relevant to ACL section 28B only if the complete consumer-connection, manipulation or unreasonable-distortion and actual-or-likely-detriment test is met. Current ACL rules require a separate assessment.

Definition

What is this pattern?

The service extracts contact information, sends or prepares unwanted invitations, or ties functionality to recruiting other people. This is a design and research taxonomy for learning and evidence review, not a statutory offence label or an automatic finding that an interface is unlawful.

How it works

The service extracts contact information, sends or prepares unwanted invitations, or ties functionality to recruiting other people. Progress depends on exposing or contacting other people, turning a referral or address-book permission into the price of access to an unrelated feature.

Warning signs

  • Contact access, recipient selection, invitation or referral is involved.
  • Consent, recipient choice or downstream use is unclear, defaulted or coerced.
  • The behaviour is linked to access, reward or normal progression.

Potential harms

  • Contacts who never used the service may be exposed or invited, while the new user loses a meaningful refusal.
  • The user is pressured to disclose other people’s contact data and send messages unrelated to the export task.

What does this look like?

These fictional examples make the design mechanism easier to recognise. They do not depict a real company and do not establish that an individual interface is unlawful.

Illustrative example 1 · Address-book import blocks onboarding

A fictional community app stops onboarding at an address-book permission screen and gives no visible way to continue without uploading contacts.

Potential consumer harm: Contacts who never used the service may be exposed or invited, while the new user loses a meaningful refusal.

Illustrative example 2 · Feature unlocked by recruiting friends

A fictional workspace keeps export disabled until the user supplies three colleagues’ addresses and sends invitations from the service.

Potential consumer harm: The user is pressured to disclose other people’s contact data and send messages unrelated to the export task.

What is a fairer alternative?

Make contact access and referrals optional, granular and previewable; require affirmative confirmation for every recipient and message.

Context matters

Context and boundary cases

  • Contact access, recipient selection, invitation or referral is involved.
  • Consent, recipient choice or downstream use is unclear, defaulted or coerced.
  • The behaviour is linked to access, reward or normal progression.
  • Boundary to test: Voluntary one-recipient sharing with preview and confirmation
  • Boundary to test: clearly optional referral program with no functional penalty

When a similar design can serve a legitimate purpose

  • Voluntary one-recipient sharing with preview and confirmation
  • clearly optional referral program with no functional penalty

Operational review

What teams should review

Teams
  • Product
  • Design
  • Engineering
  • Legal
  • Compliance
  1. What functional need makes “Allow contacts” necessary for the social app onboarding goal, and can that need be met with less disclosure or commitment?
  2. Can the dialog be dismissed, what action does each control trigger, and what later state confirms or contradicts “Contact access, recipient selection, invitation or referral is involved”?
  3. Could the stated purpose make this dependency genuinely necessary under the boundary “Voluntary one-recipient sharing with preview and confirmation”, and what product evidence would demonstrate that necessity?
  4. What functional need makes “Add contacts” necessary for the collaboration workspace goal, and can that need be met with less disclosure or commitment?
  5. Test the control across refresh, device and account states; is “Consent, recipient choice or downstream use is unclear, defaulted or coerced” still observable after persistence is considered?
  6. Could the stated purpose make this dependency genuinely necessary under the boundary “clearly optional referral program with no functional penalty”, and what product evidence would demonstrate that necessity?

Evidence to retain

  • Annotated signup and account management screenshots at each responsive breakpoint
  • The complete state sequence before, during and after the consumer decision
  • Design-system component, content, default and configuration records for the reviewed release
  • Operational records substantiating price, availability, timing and eligibility claims
  • Usability, accessibility, reversal, complaint and support evidence relevant to consumer impact
  • A dated product and legal review record identifying evidence, uncertainties and release decisions
