    Design a function that activates all critical violation flags in a content moderation system's binary flag register, where critical violations are represented by even-positioned bits in the binary number. The function should take the current flag state as input and ensure all even-positioned bits are set to 1 while preserving the existing state of odd-positioned bits, enabling the system to properly mark content requiring immediate moderator attention.
