I've never had any bad experiences with gm's on Raven when I played there. I bet if you start swearing at them in realm chat of course they would do something, I think that would apply in Horus too if Surak came on for example and some people started being really offensive with him or something. I like how Horus wz isn't really moderated at all though, hope that doesn't change. And really hope that my screen won't be spammed with giant messages every 20 minutes either.
Other than that the only thing that bugs me is I have my knight in Ignis on Raven so I kind of have to stop playing him completely as I myself don't want to multirealm on the same server. So kinda sucks because I liked alot of the people in that server.
I look forward to this though, the population increase alone is worth it for me. Now ignis night crew in Horus will have people to fight in my timezone
