Auel. The leader of probably the most known and perhaps longest lasting Military. To be honest. It wouldn't surprise me that he may perhaps he may have admin friends? Honestly. I have fought him before a while ago. Never experienced him speedhacking or anything but I'd assume maybe he has admin friends. He been on graal a long time now. So I think that's the most probable cause. As for him using staff abilities himself. Very unlikely.
It could be people thought he was banned once and he apparently wasn't and he claimed he can "Unban himself" his army is big ( Or was idk it's current size) so word spreads quick. And it would be easy for a few to say he can speedhacking and do all these things and have admin powers and can Unban and all this and it to be believed because how quick things are said and believed.
