Those... are not very professional replies from him ><. It's bad to accuse people just like that, but he does take every bad review negatively. They could been constructive reviews, but meh, low marks are just bashed on regardless. He should work on the replies XD... since they do sound childish. Tsk tsk tsk, racist remarks.
However, he is a nice Admin and tries his hardest to improve the server though some things... have changed greatly since the last time I played the server apparently o-o. Heard bad things about PvP, but that's a different topic/issue XD.
I liked his singing comments XD Though I don't like those kind of NPC messages. Same goes for some of the quest NPCs, but hopefully he'll change them soon...?
