I can confirm that its "Jokerlel", if thats some well known player, or someone using that name, or someone who is in the lobby with someone using that name at the same time.
Saw him take down TR server 3 times in the last week or so, one time he was kicking individual people as well.
Im familiar with the type. I was acquainted with a certain group of Planetside 2 PS4 players against my will last year, and while forced into their PSN group chat I saw a guy take down the whole server about a dozen times over a few months, hundreds of people boned by it each time. I dont suppose I can get into detail here but he was "urban" and absolutely thrilled with himself, and of course everyone fed him loads of attention like he wanted. Its a type I have become very familiar with in recent years.
Jokerlels behavior was almost a carbon copy of this., and of course everyone in the lobby went insane feeding him attention. Multiplayer gaming has taken a nosedive in the last decade as the playerbase became more "diverse". Every game feels like a rap video now and peoples collective IQ has plummeted.
