Can amazon detect the Nullrefer.com traffic generated by the super url of AMZtracker?

Hello,
So I discovered this tool within AMZ tracker called super URL, upon clinking the link it claims that amazon will think the product has been accessed using a particular keyword. I noticed today that it uses
Nullrefer.com to hide the reffer, my question is what are the chances if amazon will not know its been redirected by
Nullrefer.com .
anyone have had real success with AMZ tracker's…
