"Google is the best search engine…" : spam comment

Today some of spam comments are blocked by akismet. This blog quite new, so it has no much spam comments yet :). So far only 17 comments were reported as spam, compared with another blog of mine that maybe everyday Akismet will block around 500 annoying spam comments.

Usually the comment blocked by Akismet contains a live link to website that selling/promoting drugs/medicine as well as porn site. But today two of the comments is stating that Google is the best search engine… . The URL of this spam is http://google.com (without www) and the IP address is detected from Ukraine.

I am not sure what is the purpose of this spam comment. Is it used to promote google ? I don't think so. Google doesn't need to do it anymore :). Or someone actually want to try Google to ban itself because of spamming ? Please let me know if anyone knows more valid reasons about this kind of spam.
