Twitch chat is a factory of spam, flame wars and random emotes. It actually did not use to be like that though, there's a video of Trump and kibler battling in arena back in 2013 and twitch chat was very civilized. https://www.youtube.com/watch?v=FRV4JMIQPpE
One of the comments on the video pretty much sums it up.
twitch chat back then: "hello trump hope you are having a good day"
