Should downvotes on questions be “free”?
Sometimes while cleaning up old or severely downvoted questions, I'll do quite a few downvotes and close votes in a short period of time. I noticed today that my reputation did not go down at all when doing this.
Is this because I did too many downvotes in a short period of time (and the system isn't counting them because I hit some limit), or do downvotes on close votes not cost anything?
