Well, they simply do not appear to follow the redirect at all. I have set up a separate tracking table where I record the click, pass an ID along in the URL redirect, and immediately -- before any other processing -- record an entry in the table again.
In other words, if they follow the redirect and request the page _at all_, then a second entry would be recorded. That simply doesn't happen.
I doubt it's a clickbot, however, since I can vouch for the source of all initial traffic.
