My apologies to the puzzle designer and validator… the mistake was mine and once I read the puzzle description properly I was able to get 100% on the puzzle.
I was disqualifying voters if they didn’t vote exactly the number of times stated in the input, when in fact the puzzle description says to disqualify voters who vote more times than they were allowed.
I think I’ve just had a bad experience with the community puzzles not acting as described and am now too hasty to suspect that a community puzzle must be faulty.
As for finn_troll’s comments: thanks for trying to help but my experience doesn’t match what you have described e.g. my code passes test #5 and validator #5 equally well.
