I just got more than 160 spammed comments on my blog. So while I'm deleting them, I also had to finally turn on "word verification." When you write a comment you'll need to verify you're a human by typing a word that's listed. I know it will be hard for my brothers, but the rest of you shouldn't have a problem with it.
This stops the robot spammers from attacking. Many of my friends have word verification on their blog, and I hoped I wouldn't have to do it. Sorry.
