Some illegal macro users in Royals use certain unchanging parts(not covered with monsters, characters) of the map as visual “save points.” When their character moves and that landmark appears on screen, the macro automatically performs the next action. Using this method, they automate Goby, Ulu, and Skele leeching, checking the monitor only once every 30 minutes to avoid GMs—all while earning mesos without touching the keyboard. This eventually leads to real-world trading. To prevent this behavior, I’d like to propose one solution: blacking out the map(skele, goby, and some bossing maps, and so on) background for about 10 seconds at random intervals. This would cause the macros to malfunction, and GMs would be able to more easily catch suspicious users—for example, those using skills at the bottom of the Skele map or showing other abnormal movements.
you are proposing a visually intrusive and immersion breaking bot-catching method that doesn't even catch every bot.
Of course I don't know about all types of macros, but wouldn't this method at least work for those who use it?
