What do you call 'trolling'? Do you mean inappropriate behavior for a GM? Personally I have not seen any of that from him. Do you have some examples? Is he calling you guys idiots or any other names? Being racist? Perhaps he is running around PKing you for no reason?
If he is behaving inappropriately in the game he can and would, be handled by HIS bosses. All you gotta do is report it.
The point I am making here is that bit I highlighted above. It's Their Game. They are the gods of the game. The Alphas and the Omegas. Disrespect them at your peril (and trust me a couple hours jail time is the least they can do to you if you insist on acting like a jackass with them).
