Which survey link is not suitable for collecting anonymous responses?

A Personal Link is not suitable for collecting anonymous responses because it is uniquely generated for each participant. This means that the responses collected via Personal Links can be traced back to specific individuals, compromising their anonymity. Participants using this type of link are identifiable to the survey creator, as their responses can be associated with their specific link.

In contrast, the other types of survey links, such as the Anonymous Link and the Public Link, are designed specifically to allow respondents to answer questions without any identifying information being collected. The Multiple Completes Link also allows for responses from a single participant but doesn't inherently link that data to an identifiable source. Thus, using these links maintains the anonymity of the respondents, unlike the Personal Link, which does not.
