The Block Host should change the icon so that the user knows that that IP is blocked. The Block Host menu item should change to Unblock Host if the host is currently blocked. The Block Host should change to Block Hosts if the user has selected multiple files to block. The Block Host should not ask if the user really wants to block the host. Since they can Unblock, just do as they ask instead of asking do they really want to do it. BTW, the FAQ says that the Mac user should use the Apple key (we call it the Command key) but in reality, the Mac users needs to use the Control key to get the right click effect.
