"Prevent Ballot Box Stuffing" not working?

I am conducting a survey and I enabled the "Prevent Ballot Box Stuffing" feature from the survey options. Somehow, some participants are still finding a way to take the survey more than once. How are they able to do so?

    Prevent Ballot Box Stuffing uses sessions/ cookies to determine the duplicate respondent. So, if participant takes the surveys twice from different browser then he/ she is allowed to take.

    In order to prevent this, if you have some unique identifier for each respondent, then you can create a update contact action task, once the survey is completed by the respondent, where you can set an embedded data 'isCompleted' to 1. Now, at the start of the survey, ask the participant their unique identifier and using authenticator, check if they are present in the contact list, if present, show them the message they are already completed the survey and terminate them else let them continue with the survey.

    Does it possible with IP Adress, too?

    It would be the easiest way to filter doubble IP Adress...

    We working with 2 or multiple panel providers and sometimes we collect same ip adress.

    We would like to prevent the double ip adress from different providers.
