After the introduction of Vox Populi badge, I remember ever having used all the 40 votes in one day for three days. The last time was the day before yesterday. However, every time some of the voted questions/answers were deleted before the day ends -usually it are the downvoted posts. My day vote count as visible in my profile also decreased that much, e.g. 39 instead of 40, but I am unable to make another vote the same day. It shows the error that the daily limit has been reached.
Until now, I have not received the badge. Does the badge indeed require that all of the 40 voted posts are not deleted by end of day? In other words, I should not (down)vote posts which are likely to be deleted the same day? Why do I not get the vote on the deleted post back so that I can vote another post the same day?
