Is there a way to put a time limit on the prevent ballot box stuffing tool?

Hi,
I am using Survey Signal and Qualtrics to conduct an intensive longitudinal study. Participants receive 5 texts/day with an anonymous links to the same Qualtrics survey. Somehow, participants are completing multiple surveys back-to-back. I would like to prevent participants from taking the same survey within 29 minutes of completing the last survey. Is there a way to do this? The prevent ballot box stuffing tool doesn't work for me in this case because I DO want participants to answer the same survey 5 times/day - just not back-to-back.
Thanks!

      I haven't done it, but since Prevent Ballot Box stuffing uses a cookie you could potentially use JavaScript to update the cookie expiration. You would have to be able to identify the correct cookie.

        Thank you Tom. I haven't ventured into writing Javascript for Qualtrics before. I will give that a go! Can't be that hard...

          Hi
          If you would be kind to share the code it would be great!
          I have the same need and less familiar with code writing
          Thanks

            I also would like to see if anyone has developed any scripts to manipulate the expiration of the QST cookie. I want to drop an anonymous link allowing user to complete the survey only once every 3 months instead of 6.
