To Clarify, He is being kicked by anticheat when attempting to use the shake skill from an Mo fishing. Typically in a mob farm where you use shake, you would bind your place item key to a random keyboard key. In this case he was changing his controls so that the place item key was “f”. This allows the user to hold the key and rapidly throw and withdraw a fishing rod to quickly shake the mob using the skill. While many other players do this just fine hi_sseug has been getting kicked for anticheat for some reason.
When you use this method you always get kicked for anti-cheat because of how quickly it spams the rod. If you only do it in bursts you wont get kicked. I can recreate this for you whenever I play from home if needed andrew
