The title says it all, so I'm doing a local script like this
local Player = game.Players.LocalPlayer if Player.Name == "SuperSamyGamer" then game:GetService("ReplicatedStorage").Animation:Destroy() end
Nope!
The client can access and modify ReplicatedStorage, these changes will not replicate to the server or other clients.
ReplicatedStorage is replicated from the server to client. Not the other way around (Client to server), unless through means of remote events.
