By all means keep doing it. If it gets popular enough they will patch it to count suicides as deaths that affect your kd.
You are incorrectly assuming that I have used this strategy.
Even if I did try this strategy...it would be completely independent of my ability to win using "normal" strategies.
It's fun to come to conclusions based on insufficient information though.
This strategy is not boosting:
"Any user who colludes with another user to exploit the game for the purpose of gaining XP, prestige, game score, weapon level, or in-game unlock is subject to penalty."
You gain say 10 kills, then continually commit suicide. You win because of those 10 kills. Commiting suicide doesn't gain you XP, prestige, game score, weapon level, or in-game unlocks.
