So for mod spawner if I funnel mob towards me and then I kill the mod dose this break the server rules?
Mob traps/grinders are automatic looting and/or killing, and [large] dark rooms that are set up to make mobs spawn. If you found a mob spawner and made a room around it, and kill the things yourself, that's fine. Some water guiding them to you or you shooting through a window is fine.
Just to expand on that last comment "Shooting through a window is fine", it is fine but make sure the mob is able to freely walk around in the area where they are. If you want help or tips on ways to create a good environment (I don't use water) let me know via PM or while I'm in game.
