You will need to install a user script manager extension to install this script.
Whenever you join the game, it creates a new account for the session. Is good for using restricted scripts and not get banned. Your progress won't be saved but still good enough to get big and clap some noobs in the game. If you disable the script, it will switch back to your previous main account.
I am already banned, how is this good for me?
Install the script. Change your IP by restarting your router. Open digdig, then you can still play the game after ban. If you get banned again while playing, change your ip again and repeat.
