Bob is the type of guy most people would like to strangle if you ever met him face to face. Every few days, Bob lets loose with an automated submission script that spams my blog with ads for anything from casino games to debt consolidation services to mail-order pharmaceuticals. He usually does this on Sunday, when I'm more apt to be watching football with my brother-in-law than paying attention to my blog. Every Monday morning, I run another script to get rid of Bob's spam and ban his IP address.
