This is someone randomly trying to post spam to a post I wrote ages ago about why I don't have comments on my blog. Yet more reason, you ask me. You'll fight a losing battle with the spammers, especially if you use off-the-shelf software with >5 other users. Even with something you write yourself, like my my crappy script you need something non-standard to keep the spammers away.
