Well, I actually agree with BW. (I AGREED?!)
N00bs are a pathogen, and there are plenty wherever the SRB2MS'
body comes in contact with. They weaken the system, and the MS has to lie in bed while it recuperates and the mods (white blood cells) run around trying to destroy the disease. But then the MS takes medicine (easy ban button) to strengthen the mods and make them quicker and more efficient. Then the MS goes back to its normal life, with a slow trickle of germs (n00bs) coming in, but the white blood cells zap 'em off before they become a serious problem.
And then the MS gets sick again...
