Is there an official way to listen to system messages from the RBXSystem TextChannel and prevent them from being send/received? It seems that the TextChannel.ShouldDeliverCallback doesn’t work for system messages because there’s no source for the message. So the only way that I’ve found to bypass this is by using TextChatService.OnIncomingMessage and returning something else other than TextChatMessageProperties to this callback when the channel where the message was received is RBXSystem, but it spams the output with this [1] message, which although not breaking anything it’s really unwanted to occur.
