#fair play

• Anti-cheating — A measure, regulation, or technical device designed to prevent, detect, or combat technological fraud or illegal modifications made to equipment in high-performance sports (such as cycling, motorsports, or electronic chess). The term is a neologism adapted from the international concept of 'anti-cheating', used in refereeing committees to denote protocols of structural control and scanning intended to ensure fair play.
• Unsportsmanlike — Contravening the ethical norms of sports, principles of fair play, mutual respect, and competitive discipline; unfair, brutal, or disloyal behavior manifested by an athlete, coach, or supporter. Broadly, the term applies to any action in a competitive field aimed at gaining an advantage through dishonest or hostile means.
