Trying to narrow a pattern requires analyzation :) This appears to be the only type of 'visit' that isn't accounted for with my script -- I'm curious to know what they're doing that isn't sending the server variables through the $_SERVER['REMOTE_ADDR'].. I will have to keep an eye on the blank visitors to see if I can figure out what's up. Though as with any Google product, I'm not keeping my hopes up to figure out what they're doing.

Initially, I'd expected this to be nefarious visitors or scrapers.
