World of Warcraft - English (NA) Forums -> Casino Advertising Policy
Starting April 20th, all public advertising is banned. I know some of you run casino to make money but starting 20th, you'll have to get rid of any macro you have that announces in general, trade, or yell. I guess the only way to get business is to wait for someone asking for casino, then whisper the player.
So heads up, turn off macro before you get suspended or banned.
