To me it shows a community that only cares about what's said by a talking head with a camera.
If the guy was just getting banned over and over, I doubt anything would have happened. Instead he's been doing something to actively advocate trolling. A week or so ago I had an intentional feeder in a ranked game that said they were following Tyler1's example and wouldn't be punished for it, so I can only assume as recently as a few weeks ago he was advocating trolling on stream. It's worth pointing out that streamers like Kaceytron, while trolling themselves, get their viewers to hate such actions, not to follow them.
The only steamer I've enjoyed watching personally has been Voyboy. He's just so relaxed about the game and willing to take responsibility for his mistakes, it's a breath of fresh air.
