We actively monitor trademark usage to protect our community from confusion.

Our approach prioritises amicable resolution while maintaining our right to protect our trademark and reputation.

Our Standard Process

For apparent good-faith violations:

  1. We will contact you directly to discuss the issue

  2. We provide a minimum of four (4) weeks to resolve the matter amicably

  3. We work with you to find a solution that works for everyone

Formal actions may include:
