What it does is word match TF related words and sentences in a current thread to those in blogs or posts from other TF boards in order to form what deceptively seems like real on topic posts. This is how it hides the fact that it is a spambot and not a real person. It is very clever.
For example I googled his post above and found the following:
http://www.mikethepod.com/revTFUGalvatron.htm
Read the 2nd paragraph on the link, it's the same as the spambot's now deleted post.
Sky Shadow deserves credit as he spotted it first.
