HekloToday I made hack detection for the Speed hack, using command blocks. This works by subtracting the default speed from the players actual speed, and if the result is above the normal amount, the player is logged as speed hacking and a message is sent to staff.
All possible errors are taken into consideration, such as acceleration from being pushed by mobs, and speed potions.
Let me know what you all think of it! I'll post more soon like fly, and check out my other one detecting WaterWalk.
