Can you imagine we get after patch and promos external streamers going in, they get sanctioned and the evidence they get about some basic rule break like waiting 50 instead of 60 minutes to return to a system being their own stream? When the guy sanctioning could have just told them in chat about mistakes?
You know who the streamer is, talk to them about rules they break, or use your own evidence to sanction them, simple as. This isn't like in game when you can't really know who's behind what ship.
And if they break rules, it doesn't mean they are immune, it just means you can't just stalk their stream and instead of talking to them be a jerk and try to get them sanctioned - get evidence yourself like you get it in any other report. Speaking for myself it'd be damn weird to get sanctioned like this for anything but cheating/multiboxing etc.
