By the way, I just looked at the examples in your original post. Not all of the ones you listed are stolen. Not all of the ones you listed were upvoted by steemit supported dmania delegation.
I don't want to take away from your main point that a certain amount of posts don't deserve these payouts. So I also did a query with SteemData:
SELECT [Comments].* FROM [Comments]
WHERE (created > '03-11-2018 04:23:55.167')
AND (created < '03-12-2018 03:23:55.26')
AND [Comments].[parent_permlink] = 'dmania'
ORDER BY pending_payout_value
I plucked the last 15 in the result:
It's a mix of the same. Some are original, not all. Some got steemit supported dmania delegation votes, not all. I want to point out the scale, though. That's one 24 hour period from a week ago.
I don't see this as completely out of control.
I think what you're seeing is that people who get the biggest undeserving payouts have read the Dmania FAQ and are gaming it. Should Dmania address this? Sure. But I think flagging them will work too. It will have a chilling effect on the ones who are actually reading the FAQ in order to game this particular front-end. Once they realize they've been noticed, they'll move on to something easier to game.
@zombee is working on a better system. dMania is unique and it takes time to improve everything. Give him the time he needs. Right now there is a new rewarding system that makes abusing harder and harder. When more people join abusing will get even harder because more quality content will be postet. dMania is in its early stages and it just needs time to become better and better.
