I thought it was a bot too, until I got the X-Forwarded-For and overrode the storage of the downstream IP Address from the jQuery. That's why you won't find it in your server logs either. The server logs the X-Forwarded-For IP rather than the downstream IP making the request on behalf of the [non]visitor.
