I’ve added a small hurdle to the site for those who want to comment.
Just above the comment box, you’ll notice a box asking for the sum of 2 numbers. Type that number in and go about your commenting. It’s one more layer of hassle for the comment spammers – mostly to eliminate the automated comment bots that hassle blog owners by posting junk comments.
If you are logged in, you don’t have to deal with the math thing.
Trackbacks are not affected by it.
