Referral links are often used to invite new members to join online platforms, and some people prefer to make them shorter for easier sharing on social media or messaging apps. On BMF.io, each member gets a unique referral link that tracks signups and rewards correctly. However, shortening links through third-party tools sometimes breaks the tracking process or hides the source, which could affect earnings. Since the program rewards users based on valid referrals and activity, it's important to know what's allowed before sharing links. Can referral links on BMF.io be shortened using services like Bitly or TinyURL, or must they always remain in their original format to count for rewards?
