because people would most likley abuse it in public servers to make the que shorter.
and private servers have op and can kick / ban anyway.

Nah. like on bet server lot of people bet dude and then he loses.and then he will get kicked cuz vote kick .

right.. that would be a mess..

But the ops could also have a decision to either /votekick disable etc...
Couldnt they?

in games like shooters votekicks usually work because you dont want to loose an player if he doesnt fuck things up for your team intentionaly.
in toribash you either have op = you dont need a votekick since long before most ops ( at bet servers for example ) kick someone 5 players already yell "omg kick -insertplayername-"
for spammers they usually instantly /ban add and the problem is gone.
in official servers you actually be glad if you could be #2 in que instead of #5 if you just votekick the people infront of you.
and if a player spams an official room you can just go on irc and ask an gm for help / or report them in the general reports section.
i see no real use for it other than things that could go terribly wrong / disturb servers.

what id rather like to see is a permanent mute for servers just like the ban list to keep people from /rec and can talk again.
like /mute add playername and /clearmutelist or something.
would make bet servers a little quieter if someone spams all caps you mute then they /rec and yell for a nudge back to their position ( which they wont get of course ).
could reduce useless reports from players reporting the op for not nudging them back after avoiding mute ( not sure if people actually do that ) but if yes it might actually save the staff some time
