If your weblog is powered by Movable Type and Bob from bob@y*o.com (where the * is an identifier made up of 3 or 4 digits) loves you so much that he keeps posting unwanted comments to your random weblog entries, add this regular expression (regex) to your MT-Blacklist. It will stop him for sure. I added this regex to my MT-Blacklist about a month ago and, at the time of posting, it has blocked no less than 37 comments coming from him. If you are geekier than me, you must’ve had this regex in your MT-Blacklist for ages, but hey, not as everyone is as geeky as you! Not that there’s anything wrong with being a big geek. Hell, I wish I were one!
