@DeadEyeDeNNi$ The most I've banned people for lagging was about 5 mins, if I ever did. Usually I would kick them. I've been an admin too long to remember. If it disrupts gameplay for everyone, AND you've warned them, you have a legitimate reason to do so.

@Starfish If MSN lags you, you shouldn't be on MSN while playing Counter-Strike. Seems simple enough to me.
