if a thread is closed then it's closed

[Gaffer]

ok i was just thinking yesterday morning i closed a thread cause it's a petition to get a member unbanned, but the member has had way to many chances as it was and was really annoying the admin, anyway i was just thinking that there should be a hack which allows a thread to be truely closed, totally locked, maybe called a admin closer and make it so only admin can kill a thread like this and the thread has to be re-opened to post in it again, which only an admin can do as well

not sure if i'm making sence or if there is a hack out there for this
