FYI, I turned it on in hopes it will thwart some of the spammers. I was looking at the blog this morning and noticed one dot flashing on the revolver map that was off the coast of Africa. Sure enough at 6:21 am (right when I was looking at it) there was a spam comment.
I've been getting 100 to 300 a day and frankly, I'm sick of 'em.
I'll leave it for a while because it's not too hard now that Google is using all numbers instead of trying to decipher what ever the word of the day is.
Thanks for your cooperation.
