I've recently played with a player with streamer mode on also. However, this person decided to harass one of our teammates with voice chat. I asked him to stop and then he started harassing me too. there was an option to report him, so I did... but to be on streamer mode, you should have to be a verified Battlefield 6 streamer. This option with anonymity is not good for the normal player. This guy thinks that just because he's anonymous, that he doesnt have to worry about it and try to ruin the experience for a new player... the guy he was harassing was new and still learning but this guy laid into him anyway. All i know is that I better receive an email from EA that says my report was successful and he's either been banned from chat all together, or at least a lengthy ban. It was both harassing a new player and some racist tirade, and that better not be tolerated.
It is fine in regular game play where you can report people via the scoreboard but in Red Sec you can only report people via the "Recently Played With" section and this does not show what random name streamer mode gave to particular players.
Another issue with Red Sec is that the game doesn't tell you who killed you if your death results in the end of your game play in the match. For example, yesterday I was killed by melee attacks, would be fine except the closest person to me that I could see was 100m away, the ring of fire was right behind me, I was on the second story of a building and even as the camera pulled away I still could not see any players in melee range of me.
