How do you prevent respondents from taking the website feedback multiple times?

If you are trying to prevent the creative from being displayed, then add logic into the intercept to only show if the survey has not been taken. ! You can also configure ballot stuffing on the survey itself which would prevent the survey from being taken a second time.

Hi @newbie1012 I think the best option is probably the setting that prevents ballot box stuffing, though it is not perfect. Here is the support site for it. Otherwise, I think your only other options are email distribution or using an authenticator, but both of those require some previous knowledge of your respondents.
