If a violation is discovered, your access may be restricted immediately. 2.

Please do not leak confidential information or personal matters shared within the Alliance to outsiders without the consent of the members involved. - Alliance Operational Principles: The Alliance Master (Founder) and the management team are responsible for ensuring that the Alliance does not lose its original positive and friendly purpose. Should any disputes arise between members, they must strive to resolve them peacefully. 3.

If abnormal abuse is detected, the rewards will be reclaimed, and your mission participation rights will be revoked. 6. Active Utilization of the Reporting System Kertasmu trusts the self-moderation capabilities of our Pioneers. - Please use the [Report] feature on the right side of posts and comments to immediately notify the administrators of any content that violates the rules. - Reported posts and comments will be blinded in accordance with internal regulations, and administrators will carefully review them to take the necessary actions. - Let us bring these beautiful guidelines to life together, so that every single line of small records left by Pioneers today can become the seed of a brilliant miracle! 🌿 - Last revised: August 9, 2026
