What you are saying makes sense. I actually wrote a reason in my first response but changed it because of the discussion I was having.
I think people are way too sensitive about downvotes. If I disagree with someone's post reward being too high, I can downvote it. It is certainly controversial for some but remember your post can't be valued at payout time lower than 0, so I cannot actually take anything away.
I don't always have to be kind. Sometimes I want to be a jerk. Go look through my downvote history. It's is rare and a small fraction of my activity. People who know me know this.
I don't think I need to explain myself to upvote, why should I have to to explain myself to downvote?
Don't hate the player hate the game. Plenty of platforms don't have downvoting.
Do I like reward opening posts or whatever he was doing? Well not really. Do I downvote whenever I see that? Nope.
The post was crap considering a bid was placed on it. He said it was his 2nd day bidding, but he bid on a similar post two months ago. He lied.
I downvoted to get his attention. It worked. If I just commented, he would have probably said, okay sorry.
I can actually still remove the downvote, and I would have, but he was super annoying about it and even lied. So I won't.
However feel free to buy him a 0.045 SBD replacement upvote.
I don't mind people who can't invest outside money, but I definitely think they just have one less type of stake.
