2) As an admin for your site you can set it so that the comments has to be approved before it's published. So SPAM comments won't be published unless you wanted them to be.
3) The other way is delete the comments if you deemed them inappropriate, as an admin you have total control of keeping or trashing the comments.
I think you got the idea, now for the ranting part...I do mind having to enter the word verification. It takes up so much more of my time to just say, hi, I stopped by. Thanks, nice blog. etc. What's worst is the ones that tries to see if you are crossed eyed! I mean, gees, sometimes, the letters are either so blurry, on top of each other, or so mal-functioned that I can't even make out the letters with a magnifying glass!
Loose word verification from your comment form and make it easy on your visitors to leave comments.
