There’s a difference between killing someone a few times and dedicating an entire twitch/youtube presence to stream sniping and camping an individual every waking moment, verbally harassing them and making it impossible to play the game. One is pvp and the other is harassment which can and will get you banned. Which is why twitch banned advertise, because he was repeatedly stream sniping and harassing him. Not to mention it’s super cringe to obsess over a single streamer to that degree.
If the roles were reversed I’d say the same thing. It’s super toxic behavior that goes way beyond being simple pvp.
