I think this belongs in the Spam Heaven, no? As for our topic, I think it's just there to keep track of the site. I don't have an honest clue though.
It's because this page has Add's by google. It happens on all forums that have google adds (though I'm not sure why.. It just happens) (Look at the top.)
Wrong. Just because you have Google Ads, doesn't mean that you get the Google Bot. You will see a ton of search engines on here from Google to Yahoo and back again. The reason being is because they index the site. What that means is that they read everything that's posted here and put it up under various search terms. They also take a snapshot of the page to make viewing faster. For example, have you even done a google search and seen the words "Cached" right underneath each listing? That is the snapshot that Google takes.
It indexs the site so when you search it on google it might come up. Just read what capt. peanuts posted
