I am a very proactive blacklist user. Up to 500+ on the blacklist which is located at Security/Blacklist. When you scroll down the commands disappear. My suggestion is to lock that frame or in Excel speak "Freeze" that frame so when you scroll the command buttons are always visible. The alternative would be to use something like SonicWall and create a GEO-IP database for blocking by country. As I have no customers outside the United States it would make it much easier to block everyone else.
