I agree with alot that are saying, making gold in this game is fairly easy. I too played FFXI, and so far, I have had a much easier time in making money in WoW than I ever did in FFXI.
Also, I reported the one time this happened to me, but is this the norm or something in WoW? I had some random tell saying basically "buy gold at "insertgoldbuyingwebsitehere". Enhance your WoW experience with gold and fun!" Some friends of mine that are in my Guild said someone sent them a tell saying along the lines of the same thing. All the GM told me basically was, thank you for enforming them, they would look into it, and to watch out for Gnomes! o_O Wish all GMs in every game were funny like the 2 I have talked to so far in WoW lol.
