Understanding what voids a referral commission within BMF.io is important if you want to earn rewards consistently. From what I've learned, a commission can be lost when a referred user does not meet the platform's required activity level or simply signs up without becoming an active participant. The referral system is designed to reward genuine engagement rather than inactive or fake registrations. If an account is deleted, banned, or found to violate platform rules, the related referral reward may also be canceled or become ineligible. That means it's best to invite real users who intend to participate honestly.
