Blog comments

I understand the need to increase traffic to your blog. I even know why you have a bot spamming comments with meaningless banalities. What I don’t get is why you would put a dead link on your spam.

If the whole point is to increase cross links in an attempt to increase page ranking, don’t you need an actual site to link too? Even if you are trying to convince people to click a link so you can infect them with malware, you still need an active url. So why am I being spammed with 404s?

I need a plug in to deal with all the old spam bots that don’t really say anything in the comments and link to a dead url. Does anyone have any suggestions?
