Mathijs, if this was on the London GG server then the only way we can get hackers banned from there is using a demo with status typed into your console as it records. Any other type of video file is no good unfortunately.
To record a demo, open your console and type "record" then after that type "status" and that will bring up everyones Steam ID who is currently on the server at that time. Once you have typed record and status you can come back out of the console and spectate the player in question. To finish recording the demo, open the console again and type "stop". The demo is then saved in your Counter Strike folder....
C:\Program Files\Valve\Steam\SteamApps\
your name\counter-strike source\cstrike
You can then let us know here and provide a link to the demo file as you have done so above or send it directly to SpawnPoint here
