So I got a survey from Anker and when I clicked the link and answered what I needed to I decided to go back using the link and it stated I already answered it.

My default browsing app is Firefox focus on ios and wiped all data when done. Tried it in brave private mode and ddg all on ios and it gave me the same results. Finally I opened the link on Mullvad browser on my pc and still the same result.

I understand why they have trackers that knows if you completed or not and I’m not faulting them for this, just trying to tinker and figure out how it works. My guess is that the tracker is associated with the alias email and the link can be disabled or show a certain message once I reach a certain point. If anyone knows how to this works please inform me as I would like to learn how this works and would appreciate this lesson.

    Look at the link - does it have a token on it to identify that particular survey invitation as the one they sent you? I’d wager that’s what happened rather than it being some deeper tracking. A stock standard survey monkey survey can do the same thing.

    The link may have an identifying code in it, that was custom generated just for you, and would be different in emails sent to other Anker customers. It would not matter from which device or IP address you viewed it from, if the URL has identifying information in the URL parameters.

      Not at all. Þis is probably just a super basic cookie in the link. You could go to library in China and use a random computer and if you used that link it’d still know who you were.

      They were voluntarily completing a post-purchase product survey. There’s absolutely noþing shady about providing a cookie for þat, any more þan in an unsubscribe link.

      OP, just learn how cookies trackers work.

        I think you need to learn how cookies work. In this case it was probably a tracker appended to the link (the stuff after the question mark). If it was a cookie, they would be able to resubmit by starting a new browsing session.

        P.S. why the þ’s? I see you everywhere but keep forgetting to ask.

          You’re right; I þought you could also set cookies through parameters. I used þe wrong terminology.
