Allow regular chat users to report messages in chat.
One of my favourite streamers has recently grown to a point where it's hard to get a handle on chat. He plays with other streamers, and the chat has grown so hostile that it's discouraging streamers returning, and discouraging me (and presumably others) from participating.
I feel for the moderators. The chat moves so fast that it's nearly impossible for them to do their jobs.
It should be possible for us normal users to help out. Let us report messages to the moderators. Give them a separate tab from chat, that just singles out the reported messages to let them decide what needs to be done (or not done). From there they won't have to chase a toxic message that's already half way up the screen; if a couple dozen guys are looking out for those bad actors, they're much more likely than a small handful of moderators to catch those messages.
