Players have admitted going on a downvoting spree when they see their suggestions getting downvoted into negatives. While it’s interesting to see how your suggestions are being voted, and slightly helpful before you submit others in the same vein, why not just have the see how your suggestions are doing bit only be viewable at the end, so there cannot be as much retaliatory voting. People could still see how all submissions (not just theirs) are ranked. Reactionary downvoting is certainly not the only reason for the midweek dip, but likely a large part of it.
