(garbage stuff, including links to non-existent domains)

I did a lookup on most / all of the domains in your guestbook spam, and
none of them were even registered.

I did a google search using these terms:

use of non existent domains in blog guestbook comment link spam

But found nothing of value.

The IP is a known comment spammer:

http://www.robtex.com/ip/94.19.191.183.html#ip

A google search just on the IP address alone comes up with a few
examples. See this:

http://www.stopforumspam.com/ipcheck/94.19.191.183

The dns query result for dret.ddns.pl points to that IP address.

If you do a google search on dret.ddns.pl, you'll see a lot of wierd
****. There are lots of pages that show links for URL's within the
domain dret.ddns.pl, but none of them seem to work.

www.ddns.pl is a polish domain registrar. It's odd that they'd have one
of their own hosts point to a russian IP address with a negative
reputation.

As for why this bot is posting URL's for non-existant links?

It must have something to do with SEO. How exactly - I can't even
guess.
