To use this, follow these steps: 1. If you want to blacklist a user, add their username to the list "blocklist". 2. The system sends out a broadcast called "Blacklist" so add to every sprite "When I receive "Blacklist" "Hide". Do this for every sprite if you want this to work. 3. Play around with the code!
If you decide to use this, please add "Secured by PAB™" in the credits or remix this project.
