If BMF.io turns out to be a Ponzi or pyramid scheme, anyone who promoted it—especially publishers or influencers—could be in hot water. Even if they didn't know what was going on, just being associated with it could wreck their reputation. Followers might feel scammed and lose trust big time. If they hyped it up and made money from referrals, it looks even worse. In some cases, they could get looked into by regulators or sued by people who lost money.
