Until further notice the reputation system at the Blitz has been disabled. Reputations are earned by deeds and actions, and not mouse clicks.
Leave only addition of positive reputation.
And the negative reputation let cannot be given.
Regrettably that would still leave it open to abuse. I am sorry that a feature of the Blitz has been removed, but the staff was getting a lot of messages concerning abuse of the system and when it became a hassle to moderate it was an easy decision to turn it off. It does not mean it may not be returned at a future date.
In the meantime, when you think about it, most everyone at the Blitz has a reputation with or without a little system to count numbers with, and those reputations are earned by the way we play, and the way we interact with people. And those reputations are priceless in my opinion, and the only ones really worth having.
