This script works based on ping. The more you have, the less effective the script will be.
Max ping you can have in diep.io at the moment is around 10k. If you have more than that for more than 40 seconds, you will be disconnected. The less you have, the more effective this script will be.
If you happen to disconnect *randomly* (and it is not happening without the usage of the script) please submit an opinion saying so.
