Idk if you know, but he posted this on fb

He seems pretty suicidal, and at the very least, extremely depressed and filled with anger. I feel bad for him because what he's done honestly doesn't warrant him a permanent ban from Twitch. Yeah, sure he could have done all those things you said but a week or a month ban would suffice for something as small as what you said. It's not like he's constantly being racist on stream or showing blood, or showing pornography, evading bans, etc.
