Honestly, I've played since the FB version dropped and I've never really had a serious problem with staff. For me, that's a huge difference coming from PC Graal.
I think it's because Stefan and the rest of the guys behind the scenes realize that this new version of Graal is actually making them good money and they need to uphold some sort of standard when it comes to staff. Staff on playerworlds of PC Graal are dramatic, cliquey, and just corrupt and lame. It eventually drove me away from that part of the game.
Things seem fair on here though. I've been banned a single time for "speed hacking" and contacted staff by email so that we could figure out what was going on (because what the hell would I speedhack for), and a particular staff member helped me put together that it was my overclocked CPU that tripped the detection. I turn off factory overclocking in my BIOS every time I play Graal now and haven't had an issue like that since.
