How is the "vote once per day" option intended to work with the different vote restriction options? For instance, if I restrict our photo contest to only allow voting once per IP address, but also enable the "vote once per day" option, will that prevent them from voting from multiple browsers/devices on that IP address in a single day, but allow the participant to return the following day from a different browser or device at that IP address and vote? Similarly, how does it work combined with restricting to 1 vote per browser/device?
It would also be nice if it were more obvious to participants that are returning the same day to a poll allowing voting once per day that they have already voted and would just be changing their vote rather than submitting a new one.
Also, is the "vote once per day" option counting 24 hours from when the vote was cast, or calendar day, or by what?
Thanks,

Hi Dan,
Regarding your questions:
if I restrict our photo contest to only allow voting once per IP address, but also enable the "vote once per day" option, will that prevent them from voting from multiple browsers/devices on that IP address in a single day, but allow the participant to return the following day from a different browser or device at that IP address and vote?
-> exactly!
It would also be nice if it were more obvious to participants that are returning the same day to a poll allowing voting once per day that they have already voted and would just be changing their vote rather than submitting a new one.
-> Ok, we think about how we can make this clearer.
Also, is the "vote once per day" option counting 24 hours from when the vote was cast, or calendar day, or by what?
-> The votes are divided by calendar days. So all votes have the same time slots.
Kind regards

Hi Philipp,
Thanks for the quick response.
Hmm, strange. I have a poll unit with the voting period open, set to restrict by IP address, and to allow voting once per day. To test it out, I voted 2 days ago, and now trying to vote again today in an incognito tab I get the message "You've already voted. This computer is locked for further participation.". If I look at Evaluation -> Votes of the poll, I see my vote on 2025-11-21 and no others that should be from my public IP address since then (though others have voted). What am I missing? Is there a way to see from which IP (and ideally even user-agents) were cast? What might I be missing that might cause this?
Thanks,

Hi Dan,
Sorry, I was wrong about one point:
The user has to return in the same browser session and not from other browsers or devices to be able to vote on the consecutive days.
Hi Philipp,
Ah, I see. So I think if we want users on different devices/browsers to be able to vote from behind the same public IP address, even if it's on different days, we'll need to use the per device/browser vote restriction setting instead of the IP address one.
Our hesitation with doing that is voters being able to open incognito/private browser sessions repeatedly on the same day and spam additional votes. Is the Fraud Bot feature likely to catch something like that, or is it still something we should be concerned about?
Thanks again,
-Dan
The fraud bot usually catches those cases. You could require a confirmed email. Then users receive an email to an email address, they entered and they have to click a link. I would say this is the best tradeoff for security and usability for the voters.
Ah, and that's just a confirm link to click, they don't have to go as far as creating a full account with a password?
-Dan
Yes! There is no account needed
