Sorry to do this to everyone who wants to comment, but there is one post that keeps getting a spam comment (in Japanese, no less). I translated the comment and it was geared to leading people to an 'adult' site. It was not a valid comment.
So for now I'm turning on word verification, which I personally hate because I have trouble reading those letters a lot of the time and I get them wrong at least once, usually. When I want to write a comment, I just want to write it and be done, not mess around trying to decipher goofy looking letters.
However, the spammers of the world want to make it unpleasant for the rest of us, so for now I will play their game. I am hoping after a couple of weeks they will give up and find another playground and I can take word verification off again. I don't like letting them win!
