I sometimes use macros, for shits and giggles. They last maybe a week, or a day... or one-time. Never spam them.

But peoples macro's never bother me even if they do "spam" them, as long as it's not every second(or illegal gil seller spam ;D). I simply stop paying attention to them. /shug/ It's a social game. When you put yourself in a social situation, you risk coming across people with different personalities. They might find certain things funny that you do not. You can ask them to stop, but they might not. That's why you have the option to leave, or kick them if you think it's crossing into harassment.
