On Dwilight there are I think at most two such GMs with anonymous special accounts. And they don't actually access the actual code...I think. If they did get involved it would most likely be ICly, and that would involve a ton of daimons crashing into the realm in question.
In fact I recall reading somewhere that those GMs who play daimons in the Zuma Coalition are the type who are there for developing story and have nothing to do with the game code. Seeing as how Averoth, and Thulsoma for that matter, have never seen a hint of a daimon anywhere within several thousand miles of their southernmost regions, it's safe to say that those GMs aren't affecting them in any way.
