You can assume I don't complain when I get upvotes or downvotes.
They work the same way. Posts are open for 7 days, people can upvote or downvote for any reason during that time.
I didn't downvote the post for how interesting it was or wasn't it is over rewarded out of the Steem rewards and I find the idea the vote was paid for with SCT devalues Steem. It's just an opinion expressed with my dv.
