User blog:ShutUP Guy14/Closing a wiki

Is it possible to close a wiki that has a lot of staff, and I am not the owner? Wiki has been visited by many people, including people who use a proxy so I have to ask for staff assistance to block it. The reason why I want to close it is, the owner of the wiki is old (more than a year) is not active. Many rules violators and spammers, and I'm the admin That Is seems a more active than the others for a year. Can I close the wiki? Is it allowed for other person to remake a wiki That has been removed by a staff? Please help me with these questions.
