And your 2 cents matters as I had noticed certain accounts milking it a while back. They did play favorites back then and seemed to support a certain bunch. I would have thought Dtube would have more of their own stake by now as then they would not of had to rely on delegation.
Looking at their Steemworld stats it doesn't look for great reading as well as thy only have 51 000 SP and are withdrawing 91 000 Steem. The last month they have made nearly 14 000 from curation and yet they have 51 000 Steem only staked. This is not a good look for an app that had delegation in my view anyway. I probably would have taken it away earlier if I was delegating as this looks clearly like a one way street.
