Persistent Spammers

Check out the second comment to the post below this.
It's a spam message for some website about the Kennedy assasination.
Now this is the third or fourth (unrelated) spam message I've gotten on the Toad Stool so far. I usually just delete them, but it's got me wondering.

I have one of those password-protect things on here, where you need to type in the secret hard-to-read alphanumeric code in order to post a comment.

So either these guys took the time to hand-post the spam or hacker technology is better than Google Blogger technology.

EIther way, it seems like a whole lot of effort for what promises to be very little profit.
