The cross-play message is generic and sent whenever they forcibly change someones name. Your name likely got filtered because of point 6 on the code of conduct. If you have any remaining tokens you can change it, but changing it back to 'Dump Truck' is just lining yourself up for it to be filtered again in the future once they see it again. If you have no tokens remaining, then you're stuck as Redacted until they issue people another token in the future.
