Except mods are often ineffective if they resort to using novice creation to insult (which they did tonight), so you really need GMs in general, and they are already trying to hire.
We have a couple of AM GMs, and mods around for that matter (Or atlest, I know the mods at times have contacted me as I was the only GM online), but we can't be on 24/7.
I'm usually available, but can't be ingame and monitor all the time. But if you send a support ticket once it starts happening, I'm usually able to login within 5-10 minutes...
