Why are so many Guests "Viewing User Profiles"

Attachment 8842

I've never looked at the "Who's Online" feature of the site. lots of Guests looking at user profiles.

At a guess, I would say that it is bot traffic. Bot being the term for a automated software to do a task. Some of that is spam related bots, and some would be search engines crawling (or trying to at least) through the site for indexing. Another common category for bot traffic are hackers poking around.

Bots

I have not bothered to poke around and figure out exactly how viewership is being tracked. In general, it is easy to track when a page is loaded (an http GET request) but a bit harder to track how long a page is being viewed especially on an intermittent connection. I would guess that when a bot is loading and scanning hundreds of pages, nafex might not be tracking a page being closed and it might take a while for the 'view' to timeout. That would make it look like hundreds of guests are viewing when it may only be one or two bots actively scanning.
To investigate farther it might be interesting to look at more information about each 'guest' (see if most of them are from the same IP address, etc).
