also you can go into blockand/base/config/server/prefs.cs (i think thats the name) and change them there. And my brother is 8 and i wont allow him to play online.
That is correct, but you'll have to host the server to have your word filters work. File can only be edited when Blockland is not running, otherwise when you exit blockland it will undo your changes. I'm sure, but not positive, if you do edit it, and execute it mid-game, it should save. Type in console, exec("base/config/server/prefs.cs");
