Fair play to them. Host it for a few months, take your earnings and go live on a beach in Bangkok somewhere where blizz cant find you.
Makes you wonder why people dont just play official wow and pay a subscription. Personally wow was fun when it was a challenge, official servers are too easy now anyway, a server which is like x50 exp or you can just buy level 80 doesnt appeal to me in the slightest.
Each to their own, I guess.
