Hello everybody!
I have created a survey which I want to prevent from repeated participation. The setting "Use cookies" is set on "yes", however it's not working - I can access and fill in the survey repeatedly from the same web browser. I can't use tokens because the survey must to remain confidential and participants cannot receive tokens on their emails. Is there something I can do about this?
I know that using cookies is not the most safe solution (just deleting cookies from the browser) but this is a minimum I suppose I can do about this (at least to discourage people to do more than just access and fill in the survey again)
I use the 1.91 version of LimeSurvey.
Thanks in advance to anybody that try to help!
