Stream sniping is when someone watches your stream to get an upper hand to essentially cheat against you in a game. For example, they could find your position on an open-world map, find out where your base is, or even find out when you're low on health, so they can ambush you. It sucks. The deveopers of Rust, Facepunch Studios... are (to my knowledge), the first game developers to build a preventative measure against it into their game. They call it Streamer Mode.
Once I finally got some good loot, I was attacked by a stream sniper, who then stole all of my loot.
Consists of a 10-15 year old virgin that is trying his/her best to get in a game with a popular streamer such as Ninja Tfue etc and the goal is to kill them and get a great reaction whilst they're streaming they're also watching their stream to see updates such as if the streamer is low health idle or being attacked by others in the game.
Virgin: Dude I'm in their game I think *Wets pants* DUDE I'M IN THEIR GAME I'M GONNA FIND THEM AND KILL THEM
Virgin: *Kills Streamer* OMG I KILLED THEM I KILLED THEM I KILLED THEM...
Cool guy in party: Dude chill tf out you killed someone it's not like if your parents loved you.
Streamer: Fucking stream sniper man *reports stream sniper*
Virgin: Dude c'mon i'm going to get banned now *cries*
