While coding you can limit the Stacker to a certain amount of props, so if you were to set it to 1 and lock it you would be able to somewhat stop spam... (And with the help of Ghosted Props). I see the persicion as a very helpful tool. The stacker can make a wall slowly if set to 1. Before another server (that shall remain nameless) shut down I played on it for 2 years and it almost because I can't say never that would be a lie, had a problem with it. I was admin on this server so I had to deal with all kinds of shit like that constantly and if you do it just right you'll be able to, somewhat, Troll-Proof it... As I said, It says in console if (for admins/mods) if someone spawns props with stacker and if they spawn a lot at one time, well, check them out. But it was just an idea, the stacker.
