The link you received is definitely unique to your Ethereum address (the one that you used to send the 0 ether transaction).
Here is the affiliate link your system gave me:

Can you see why I might question whether it's unique and tied to my ethereum address?
Perhaps you could explain how this works. If you can tell me the ethereum address this link is tied to, that would convince me.
