That is just a Google bot doing its job, which is to go around the Net and collect information. I thi nk you can see the various bots listed in the Who-Is-Online list at the bottom of the home index page. There’s nothing about that that is bad. In fact, to help people find something during troubleshooting it is a good thing.
But it should be noted that a bot can be blocked by the site webmaster, so it’s not like Google is forcing site owners to allow the bot on the site. It’s optional.
