Why do I keep getting punted?
 

One of the reasons you could be getting punted from servers is you are using skins. If you can join a game, but get punted about 30 into it every time that is most likely why. make sure your shortcut for dflw does not have any / commands. And that you don't have mod666 or other skins installed.

Also, make sure your weapon wecoil, scope drift and crosshair spread are set to on in your player settings.

There is one more reason you could be getting punted. If the server has Weapon recoil, scope drift and crosshair spread turned off, you will be auto punted one time. If you rejoined and you didn't get punted then that was the problem.
