In order to avoid unhealthy hostile behavior and emotions, increasing hostile emotions and behaviors between team supporters is not a desirable goal. However, analyzing the factors that may lead to such an outcome can help us better understand and manage these situations to promote a safer and positive sports environment. The following are ways that may exacerbate fan hostility and behavior (but these methods are not recommended for actual operation): 1. **Media hype and hype**: The media can increase tensions by highlighting any historical rivalries or disputes between teams. Excessive coverage of conflict events may affect the emotions of fans. 2. **Social media interaction**: Heated remarks and provocative posts on social media platforms can spread quickly and may cause disputes between fans supporting different teams. 3. **Vicious competitive culture**: If the hammer throw or sports activities are overly emphasized on competitiveness rather than friendship and sportsmanship, it may lead to more intense confrontations. 4. **Inappropriate advertising and publicity**: Marketing activities that use negative emotions or confrontational language can increase the hostile atmosphere between teams. 5. **Alcohol and substance abuse**: Excessive drinking in stadiums or viewing parties can lead to emotional outbursts and impulsive behavior. 6. **Unfair or controversial refereeing decisions**: Refereeing decisions that are not accepted by fans may arouse resentment and hostility from the audience. 7. **Historical and cultural factors**: Games involving historical or regional rivalries may be more likely to provoke strong emotions and hostile behavior from fans. To mitigate these negative effects, organizers and communities can take measures to promote team spirit, support fair play in sports, and encourage fans to show respectful and civilized behavior.
