What can be done against QUITTERS?

[sh0o0o]

I've had enough of noob players that log in and out in deathmatch games after killiing 1 player. I was thinking that maybe a certain amount of times to rejoin in the same room should be limited in order to avoid these bad players that the only thing they wanna do is to bother players who only want to play fairly. 

I've seen two players doing that ALL THE TIME, LITERALLY ALL THE TIME:  "M4GIC" and "Makenzie_" 

Thanks
