If you are browsing AL, you agreed to it at one point, and you have a cookie on your computer. If you had not agreed, the site will not work. I won't agree to it, so I can only see a little of any referenced listing.
Nope, scripts disabled it works fine. Enable scripts and get the popup which if I decline redirects me to google. Disabling scripts again and it works again.
No cookies in the standard places. Perhaps they do whitelisting by IP address, I am on a dynamic address.
