The following is a portion of the Player Rules which can be found here:

Quote*Macros must be quiet - no saying pointless things, or making NPCs constantly chatter
*AFK Macroing is defined as any macroing where you are not paying attention to the game screen - this includes reading or posting in the forum.
*All AFK Macros must have an 8-10 second gap between actions. Players will on occasion be asked to respond by GMs if they appear to be macroing. Non-responsive players will be jailed and disconnected.
This should also include any sort of spamming, especially in public areas, such at the Meadow, or over public chat. I will be adding that in.
