I believe zer0 said, if the admins beleive something is unfair, or to one sided, the admins can take a vote to ensure that no players are allow to use the spot or the thing players are complaining about.

He said something along the lines of that, within the forums...

So pretty much, if admins think that fast zombies are unfair on escape maps, admins have the rights to make them "illegal" to use. We can just freeze players who are fast zombies to make it more fair.

Whyt, you know that the fast zombies move to fast? There hitboxes are incredibly small and are hard to keep up with.
