It happens, just the votebans don't succeed when admins are in the server. People do attempt votekick/voteban for this, really surprising you haven't seen it.
It's just easier to pass along the info that this is a gungame server, and no normal player or normal admin would likely ever have the authority to enforce it without repercussion. And that attempting to do so should be seen as a no-no.
It's been brought up quite a bit, and suggested that a plugin may be implemented, but the fervor surrounding the prospect died within a week, which to me shows its true support.
People in the moment say "Yeah! Let's do that!" and in the moment, they have fun doing that. Until one person doesn't join the horde and they feel betrayed.
"One of us." They cry! "Get the outsider!" screams another. QQs and salt flies all around, votebans and kicks start. This angers the gods, and they respond in kind.
