Sorry, but you do not work for Dtube. What makes you so certain you know what Dtube should be about or for? Do you work for it? No. Do I work for it? No. None of us know what Dtube creators really want.
As for "without any work of my own" well, my expert curation and selection of these films from being MFA in film direction, not to mention finding good copies, converting, uploading them, finding good quotes (and honoring them).. it is all plenty of work - in fact I'd be paid well for this expert work on a TV channel for example... much more than anything I could earn from steem.
And i've been meaning to write short personal criticism/review of the films to go along with them... but I decided to add that later as just all I mentioned above is quite a lot of work. It's a film school basically. Educational purposes. I was a film student once and I remember how frustrating it is when you want to learn but can't find that obscure fantastic film you've heard about but hollywood doesn't give a damn anymore.
But I digress. What I do know is that neither of us know. So I suggest, as a compromise, that you contact Dtube in some way, discretely, and point my channel to them. If they tell me they do not want that stuff here, that it will be detrimental to their platform, according to what they have planned for it, I will gladly erase everything they object to - which will be more effective than any flag which makes content only less visible.
