What it does

Add kick at the end to remove them now. Run writeid afterwards to save permanent bans to banned_user.cfg.

Good to know

Bans are lost on restart unless you run writeid.

Run it on your server

On a SLASHPLAY server, type it in the Console tab of the server page; the reply shows right under it. A value set there lasts until the server restarts. To keep it, add the line to cstrike/cfg/server.cfg. New to this? Start a CS:S server first.
