DayZ - US 232 - Player named "Administrator" using combat disconnect (alt+F4) and kicking players when killed

[Takaara 1]

On Server DayZ - US 232 about 3:40am Pacific time (3:40pm in game) I shot 2 people and before they actually died, both of their bodies disappeared and about a minute later the second person I shot showed back up and when I shot them again there was notification that "Administrator was killed by Takaara (Friendly Fire) - Administrator was killed" And immediately after that I was disconnected from the server with a message of "You've been kicked from the server". I'm a new player (first time playing let alone first shot fired...) playing with two experienced players who received the message on their clients and in the room watching everything that happened. From what they were saying, kicking and/or banning people from a server for pvp actions is unacceptable. If this is true, I hope the problem will be addressed properly.

Most likely that is the name of their Windows account, since your Arma character will have that name by default.

I got kicked from a server three times yesterday when... nothing happened.

It's likely that you are not seeing related things, but not impossible.
