Check what the ip-address is of the visitor(s).
My site isn't public yet either and I noticed that ip-address 66.249.65.*** is a regular visitor.
I've installed the module myReferer and this came up with a Meta Crawler called
msnbot (+http//search.msn.com/msnbot.htm).
The ip-address mentioned above have been noticed on other sites (ie. WF-Projekts) with XMMemberstats installed also.
You should configure the file robot.txt the right way. More info about robot.txt and a validator can be found here:
