Part 2: FTC Enforcement Guide

The 2024 FTC Consumer Review Rule

Effective October 21, 2024, the FTC's new rule makes it illegal to:

  1. Create fake reviews - Writing or buying reviews from people who haven't used the product
  2. Use AI-generated reviews - Without clear disclosure
  3. Engage in review gating - Selectively soliciting only positive reviews
  4. Suppress negative reviews - Preventing legitimate negative feedback
  5. Buy positive reviews - Paying for reviews (unless clearly disclosed)
  6. Operate fake review websites - Creating sites that appear independent but aren't

Prohibited Practices

Review Gating (Illegal)

PROHIBITED:
1. Sending satisfaction survey
2. If positive → ask for public review
3. If negative → direct to private feedback

This "gates" reviews and is now illegal.
