Keep track of what people are spawning, is this possible? Maybe it should print to the console or something.
If its spawned by a trainer its basicly impossible. If you write scripts for it you could track&trace anything.
Hmmm. Because I have people joining then spawning tons of planes lagging up the server. There is no way to keep track of the people doing that?
Nope, either kick/ban them or disable ScriptHook usage.
