It's your opinion because you are looking only at the chart. You are not looking at the daily contribution of people. They all work hard to improve. It's the same for other apps, utopian, fundition oracle-d and others.The more you contribute in them the more rewards you get. That's it. And if I'm the most upvoted, that means I worked a lot, I cintributed a lot and all the upvoted people as well. We spend hours creating our videos and watching others to improve. If I record home, that means I don't have the opportunity to travel. I interviewed more than 80 people for dtube. I created more than 300 videos. I work hard to verify all new videos to make sure people are not stealing content. I reported to dtube moderators a lot of spammers and such people who steal videos from youtube and put it on dtube.
The hidden name in that chart is me, I just don't want to discuss that and send the link here to verify. Dtube curators are doing their best to upvote the quality as well. I can show you a lot of greate videos upvoted by them. But if they missed someine it doesn't mean they are bad. All the upvotes are manual and it's very hard to curate so much videos manually.
Thanks for caring.
