Reprogrammed BonziWORLD server with a couple new security features. Works basically like vanilla bonziworld but without all the vulnerabilities. No building required! No built-in banning or kicking though, that's for pussies.
Node JS, Socket.io and That's it!
Run the command "npm install socket.io" in the same folder as index.js. Then run "node index.js". Finally go to http://localhost. If the port is taken, change the port in the config.json file and go to http://localhost:WHATEVERTHEPORTNUMBERIS
