Scripting is the ability to enhance the user experience.
Each server has a section in their Rules section relating to it. To see the full set of rules click one of the following server links: US and EN. Here is the brief quote from the specific section as it relates to scripting:
Using a program as interface between the player and his game is prohibited. Any other form of automatically generated information generated for a group of players advantage with malicious intentions is forbidden as well.
This includes but is not limited to:
Automated island databases
The Test Server does not monitor enforce any rules and regulations, thus you can use any and all scripts there without fear of a ban.
WikIkariam does NOT condone or recommend the use of any scripts on this or any other server.
