How can teams tell their fans apart from others?

Teams can differentiate their fans from others by observing their unique behaviors, such as wearing team merchandise, displaying team colors, and participating in chants or cheers during games. Additionally, teams often engage with their fans through social media, where loyal supporters actively interact and share content related to the team. Fan loyalty can also be measured through ticket purchases, attendance at events, and participation in fan clubs or forums. These indicators help teams identify and recognize their dedicated fan base.
