Why do you want to delete the status? Why don't you just block it?? In case you want to delete it, and there is no option for it, use system admin access, go to admin console and delete it. If the system hangs, try checking the DB for inconsistancy or try to clear the cache before doing so.
Hope this helps...
PS: It's always better to block the system created options, incase you don't want them.
Modesty is good!! But remember, all your life other people will try and take your achievements away from you, don't make it easy for them.
