hehe i bought 9,000 wow gold altogether, and i share an account with my brother too, and have said several times "gtg my brother is coming now" etc, because i didnt actually know sharing was against the rules(obviously like most people i cba to read the HUGE page of rules - obviously i never say anything about account sharing in game anymore) and well i always swear ingame, maybe i am just lucky that i have never been warned? nothing has never happened ;P
edit: just rembered i have had one warning, my warlock was once called "Satansservant" and apparently blizzard said it was offensive so got a warning for it
