AYK, A user can up-vote or down-vote posts when they reach the threshold of 15 reps. If they have lower reps their votes will be recorded until they reach the required threshold.
My question is that if someone's reputations come back to below that 15 threshold, will their votes get erased?
If yes, is this fair for the post-owners who have received those votes when the voters had at least 15 reps?
