Design a system to detect bot players.

Focus on outlining the key components of a bot detection system, including data sources, algorithms, and user behavior analysis. Discuss how you would gather data on player actions and identify patterns that differentiate human players from bots. Consider incorporating machine learning techniques for real-time detection and the importance of minimizing false positives. Be prepared to explain how you would iterate on the system based on feedback and evolving bot strategies, as well as how you would balance user experience with security measures.
