Seems odd to specify Chinese gold sellers in this server announcement:
Are the Chinese the sole target of gold-selling efforts, to the exclusion of any other country? (My own quasi-sincere initial reaction was "how will I know they are chinese? the character-sets used aren't logogram/hanzi characters!)
I suppose my suggestion would be to merely leave it at "If you see a gold seller spamming your chat...", or if you think that will detract from the occasional person who spams their efforts to sell on the market, then perhaps "...see a gold seller spamming with non-Warmane gold services...".
