I don't really know who the Graal Police are these days. But anyway, I know Guri has been GP for a few years so he/she(sorry) must be very good to hold that position for so long. Jarace is actively resolving issues on the forums and he's always answering questions in-game.

All GP should be reliable and i'm sure they do a great job, but personally I would contact the most experienced GP's. If it's a huge problem but does not require a ticket to be sent, i'd contact a GP admin.
