Will pyro get banned? Probably not, SE isn't going through youtube or twitch looking to ban people.

Could he get banned? Yes, as shown with the streamer that was recently banned, all it takes is a group of people to report him.

I think the part that people are most upset about is the fact that the use of addons has turned into a report war, which is what the players and the developers did not want. So the conversation around what is cheating what isn't is not what people really even care about in this situation. What happened just shows how people can sway SE with mass complaints. It is to bad that does not work in job design in this game though.
