On the Who's Online page, I have it Profile Display set to Guests and Show Bots set to No. I'm seeing lots of bots, but they're display as "guest" not "bot". Example:
User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/534+ (KHTML, like Gecko) BingPreview/1.0b
Host: (msn.com) msnbot-65-55-217-219.search.msn.com
It shows as a "guest" from Redmond, WA.
