Unsafe? It’s not unsafe to laugh at you for quitting a casual duel and wasting my time. What would be unsafe is making threats to find you in real life or continuing to follow you in multiple duels, call you names, insult you, etc.
You have very thin skin for 2022 and should work on that. People are going to say and do mean things. Again, you can turn off chat and even just mute spectators only so outsiders won’t be seen. No one, even other mods, are going to moderate what happens in chat. That is why we have a disclaimer.
