The NCAA and campus athletic programs report a surge in abusive and threatening social-media messages directed at student-athletes, particularly in men’s college basketball around postseason play. Players report doxxing, harassment and credible threats tied to online gambling activity, forcing athletic departments to increase security, legal coordination and mental-health support. Coaches and compliance offices warn the volume and specificity of online abuse has tangible effects on player performance, retention and well-being. Universities are updating reporting protocols and partnering with law enforcement as the NCAA analyzes data to guide prevention and response measures.
