Oh no no no... I've done MUCH worse before in some of my suicidal matches. One time, I played a game where all I did was: spawn, throw 2 smoke grenades, kill myself, spawn again, throw 2 smoke grenades, kill myself....... I think I ended up something like 0-52 by the end of the match. Truly a remarkable game! Obviously, I wouldn't recommend trying this as much as I have if you care even a little bit about your overall KDR.
