Yes thats correct. I’m a moderator and there’s nothing rude about following you to a duel. As we’ve stated as a disclaimer in settings for Chat that we do not moderate chat and you can turn it off. Chat is disabled by default. Otherwise, you accept the consequences.
Joining your duel to laugh at you surrendering when you used an OP earth machine deck is not harassment. It was one game. I didn’t follow you through multiple duels.
In the future, if you can’t handle chat in-game, turn off chat. The setting works in real-time, even when in a game.
