Shared Ban list warning should apply for all messages, not just first time chats
The Shared Ban list warning should apply for all incoming messages, not just the first-time chat.
Example scenario: A user chats in my stream, doesn't say anything ban-worthy, e.g. "Hello." They say something to get banned by someone who I've shared ban lists with. I want to know that they've been banned but the current implementation will not share that information.
The current implementation makes it quite easy for a bad actor to evade these warnings. Also, it's unlikely that people will open with something offensive unless they truly are trolling.
For this feature to truly be valuable, we need to know that they've been banned in general, not just check the first message.
As a streamer, I want to be notified if the people chatting in my stream have been banned by my shared ban list friends in general, not just the first-time chat.
