Luna Online has an anti-botting feature called Auto-note. It is basically a very simple color matching puzzle that players can use against suspected botters. The consequence of failing to solve the puzzle within 2 minutes is an automatic 1 hour ban from the game. This feature has confused a lot of people (and caused a lot of unnecessary bannings of newbies) so I will just make a guide just in case people need it. AutoNote can only be used on field maps and cannot be used while in town. So it's a good idea to AFK while in the safety confines of a town.

AutoNote puzzles are a simple color matching puzzle. To best show how to answer it, imagine the colors as being marked with letters A B C D (from left to right, top to bottom). The system will show you random mix of ABCD and you simply click on the correct sequence of colors.

In this example, the question is D A C D. Simply click on the color black, then red, then blue then black again to answer the questions correctly.

Note: This can be a problem to those who are color blind. So if you are color blind, then you're out of luck.

Note: In the current situation, botters have discovered a way to disable autonote and you cannot use autonote on them (it will simply display an error message). This is a sign that they are using auto-note protection/game client hacking and you can report them to the GM. This feature can also be potentially abused by some players on unsuspecting newbies who don't know how to solve the puzzle and gets temporarily banned.
