I first saw a hit from them at [25/Aug/2005:19:35:34 +1200] on an image that is hotlinked to (with my permision) on quite a few sites.
When it does request a hotlinked image it doesn't request robots.txt first, however it does before requesting an .htm page.
Yes, i see the delays between the main page and the items included as well
which is a lot more bot like behaviour than an actual browser.
So very interesting behaviour characteristics.
