If you see someone doing it, you should ask them nicely to stop. If they don't, add an admin and tell them about it. If they refuse to do anything about it, try another admin. If all else fails, Save the replay (demos can be found here: http://www.ibisgaming.com/...Links-to-Demos. Make sure you are using something FTP compatible. Then go to the rules section and read the stickies. Figure out what rule he broke, and what you can maybe get him banned for. Even if it is only a temp ban, you will want to follow this process. Simply having a 1 hour to 1 day ban on record is important, as it allows the admins to spot repeat offenders which will result in longer ban lengths. Doing this helps allow for better servers.
