I´m new here before say how is that and how to ban i just wanna say that i have a server ( net.connect server.baarust.com:28085) i see a lot of hackers usually they are americans maybe because we are brazillians and they hate us.
Well, they kill everybody he get´s close, you just broke your legs and die and appears on screen that you suicide.
How to ban??
They have a anti-ban system and somethings like that, i have Oxide mod on my server, well i cant ban him through id or nick, or i can´t tp(teleport) to him and can´t kick , you need to record his Steamid64 go to the Ftp on your server and add this to your banlist and then restart the server, it´s boring but is the only way.
How to get his steamid64?
You can type (has admin) status on F1 will show to you, or go to steam (in-game) show all players enter on his profile, i use a steam converter he convert his steamid or his community profile into steamid64. (Have others by i use this one, http://steamid.co/)
hope that i help
