I see, I always recommend take some time and do a short little intro acknowledging dtube/steemit, doesn't have to be a long or fancy thing but just letting people know it is actually you, there are a lot of people that can just take someones content old content from youtube and post to dtube. So unless its 100% verifiable it won't get an upvote at least from what I have seen, just trying to help out sorry if I came off the wrong way. I really like what you do and dtube prefers new content to be fair with other platforms even if it's posted elsewhere not a problem. There is nothing wrong with uploading old videos they just most like won't get rewarded.
