Ballot Box Stuffing and Respondent Tracking 

Before a recent upgrade, it was possible to design a survey that prevented ballot box stuffing by checking against the userid for a particular survey, not the computer (i.e. browser cookies) from which the survey was submitted. The old procedure follows:

1) Enable the "Prevent Ballot Box Stuffing" option in Security
2) add &responseCheck=false to the survey link in the email invitation.

The &responseCheck option has now been disabled and there is no way to deliver this type of survey to the user. It is practically the only type of survey that I deliver. (The documentation still refers to the &responseCheck option, and I spent hours trying to diagnose a problem with a survey that used to work.)

1. I frequently have several users using one computer and I imagine most folks can't be sure that their population don't use shared/public computers
2. I do not want users to complete a survey multiple times for various reasons. It is confusing to the user and I don't want to "decide" which responses are valid.
