Add an option or splash screen for hints/spoilers (available when streamer chooses to allow/deny spoilers/hints)
I watch a lot of streamers who are extremely picky about people dropping hints/spoilers in chat. Often times people innocently will drop hints/spoilers only to be scolded or muted or banned. It would be nice if there was a "hint's/spoilers" button that highlights on or off in chat that allows you to send hints/spoilers via a special highlighted message in chat. (This might help prevent people from accidentally posting hints/spoilers). OR when you enter the stream it gives you a warning like the "this stream contains adult themes" are you over 18? (press yes or no) splash screen. But in this case it could say "this stream is not open to hints/spoilers" press yes "if you agree not to type spoilers in chat and enter this stream".
