EDITED FOR CLARITY:

So I toggled the community spacing, refreshed and I don't see how you can see if a thread has been downvoted. It only turns purple if you downvote it. What kind of script are you running to see thread downvotes?

With community spacing toggled on you can't see a thread downvote arrow at all. Not only that but if you had the community spacing toggled off you still wouldn't be able to see if a thread has been downvoted.
