At the moment not many people /y a vote-kick, usually vote-kicks fail and hopefully administrators and moderators are able to enter the game and decide what needs to be done in the event of hackers or griefers. I suggest a few extra features to stop griefers from ruining structures and bases while administrators are unable to respond. This suggestion is a togglebuild feature. For example. on many servers the vote-kick may get around 5 players who actually hit /y when a griefer is destroying their base, while the other players do not respond to the vote-kick for their assorted reason. So I propose that in addition to the customised vote threshold for a kick, there should be a customisable threshold for a togglebuild.
What this will do is, in the case of griefers only receiving say 25% of players voting, while they are not kicked from the server, they are banned from building and destroying. This will force many of them to engage constructively with their team by only being able to attack the enemy. It also means that players who are vote-kicked by trolls aren't completely kicked from the server, they can stay on and prove that they are trying to contribute to the game in a positive manner.
