Left 4 Dead 1 Server crashing/lagging tool/script

[Trishhtan]

I am requesting something along the lines of a script I can bind to a key that causes a l4d1 servers to lag/crashor a tool where i can simply click "Lag" or "Crash" and it will lag/crash the server.
The reason I need this is because everytime I click versus->quick match It goes to a campaign mode game that I guess is set to versus or something.
It's really annoying as I do not want to play a Left 6 dead server, I only want to play versus -_-, Also I tried setting "Custom server content" to off and that did nothing.
Basicly I'm quicksearching versus games and it keeps putting me in a modded campaign game.
