Deleting a specific vote for a participant in a video contest

We have some participants who are voting fairly for the most part, but have some votes that should not be counted as it seems unfair to the contestant. Currently we have to delete the voter which deletes all votes (good and bad). Is there a way to selectively delete some votes without deleting the voter?

Hi Bolly,
I'm sorry, but you cannot delete single votes of a user, but only all votes. This does not delete the voter.
Kind regards
