about Lucky
Lucky is a defensive Minecraft server scanning and warning network. We look for personal servers before griefers find them, warn the people who run them, and keep their addresses out of public view.
[why Lucky exists]
The idea behind Lucky is more than ten years old. When its founder was young, she spent her monthly allowance on Minecraft servers for her friends. Three separate worlds were vandalised or destroyed. Some were meant to be public but were poorly protected. Others were meant to be private. None had a whitelist.
The people who found them had scanned the address ranges of a popular server host. She did not know that at the time, but the experience stayed with her. As she grew older, she watched the same thing happen to other people and realised it was not a run of bad luck. It was a systemic problem.
Lucky began in 2020 and became a sustained project in 2023, when there was finally time to develop it in earnest. The aim was simple: build better discovery software than the people looking for worlds to damage, then use that advantage to reach server owners first.
[finding the servers others miss]
Lucky has been developed continuously for more than four years. It runs without stopping and does not rely on fixed assumptions about where a Minecraft server ought to be. Its scanning system learns from each discovery. As the public internet changes, it redistributes its scanning work.
That approach finds servers in address ranges and on ports that common public tools overlook. It has made Lucky the most effective Minecraft scanning and warning project of its kind. Its aggregate results are published in the public census. Individual server addresses remain private.
[discovery is only the beginning]
Finding an exposed server does not protect it. Lucky's automatic systems try to distinguish personal worlds from servers that are plainly intended for the public. When a personal server appears open, a bot can join, explain the risk and leave. When a single chat message is not enough, members may leave a sign where an owner will see it or try to contact the people responsible.
Members use a private client to visit randomly selected discoveries and piece together the history and ownership of a world. This Minecraft archaeology helps them identify and contact the person who can protect it.
Later probes and member rechecks often meet a newly enabled whitelist. That tells us the warning reached a server owner who acted to protect their world.
[the people behind the network]
Lucky is an invited volunteer community. Many members have lost a world themselves, or understand what is at stake and want to prevent the same loss for somebody else. Some were already visiting exposed servers on their own, leaving signs and warnings one world at a time. They joined Lucky to do that work with a shared scanner, a private client and other people pursuing the same goal.
Not every scanner is malicious, and Lucky is not the only group trying to help. What distinguishes this project is the scale of its discovery system and the human effort attached to it. An unexpected warning can be unsettling, but it gives a server owner the chance to act before somebody arrives with worse intentions.
