Fraud Bot

Started 26 January 2022 by Michael Bann

Is there a way for PollUnit to review a contest of mine with a specific entry to get a sense of how accurate the Fraud Bot findings are? I have one that spiked recently and Fraud Bot indicates up to 50% suspicious activity. I would love some additional feedback on that before I take action.

Hi Michael,
can you send the link to your PollUnit to support@pollunit.com (please don't post it here).
And also which option we should review.
Then we can have a look.
Kind regards
Philipp

You can see the voting time in "Evaluation" -> "Participants"

Hello
We have some issue about fraud bot.

  1. we have an canidate who increased his votes form 50 to 4,000 in just one night. His mother is our colleague and she said that she didn't do any fraudulent multiple votes. So, we want to know why this situation happened?

  2. We used the fraud bot to detect the suspicious voters and deleted it, but after we deleted the suspicious voters, the system still shows warning percentage of suspicious voters. What does this mean? It means our deletion are incomplete?

If you clear all suspicious votes of an option we do not automatically recalculate the percentage of fraudulent votes. This happens because in most cases cleaning the voting happens after the end of the voting period. So you still see the most suspicious options.

You can recalculate the fraud bot score in the context menu of each option or for all in the fraud bot index (click fraud bot in the evaluation sidebar)

But it just happened after we cleaned the voting, why?
and the first question, we didn't have your answer

The first question: You have some bad actors on your poll. How to prevent this is explained here: https://pollunit.com/en/tutorials/prevent_multiple_participation

In a nut shell: You can prevent fraudulent votes only when adding some hurdles for your voters. To make this 100% secure you need to have some authority who's willing to vouch for the identity. This can be done with our invitation system or using your own SSO provider.

But it just happened after we cleaned the voting, why?
If you clean / delete fraudulent votes we delete this votes but do not update the fraud bot score, so you can access this information afterwards. If you click recalculate, the score will be updated. But maybe I didn't understand your question correctly?

One candidate can only have one vote for one participant, but the participant has many votes to vote, right?

Yes correct!
