Going on 2 hours of radio silence after logging in to find my character in GM jail

Someone is either exploiting the game on the server level/ packet level, or a GM is being very unprofessional.

I'm leaning towards the latter.

I've never heard of any kind of hacking that allows you to straight up warp players into another zone, let alone while they're offline. That would basically require a normal player to somehow gain access to GM abilities and you can bet people would do that regularly if it was easy simply due to the sheer chaos they could cause.
