What annoys me is that your whole belief of steem depends simply on whether you earn or not. Do you know about SMTs, communities, the scalability, the proposal system? Does all that go out the window simply because a whale is bullying you? Bad situation for you but doesn't mean the system as a whole is broken or not worth believing in.

You make it seem more unfair than it really is. You were uploading 1 minute videos answering an easy question and getting top rewards on the platform for a while. I can't speak for @ocdb but I would guess that they thought you got too much for 1 min videos.

That said, I think downvoting you that much is unfair, but your reaction isn't good as well. Instead of trying to understand why and talk about it you straight up throw a tantrum threatening to leave steem.

I'm never happy to see content creators leave steem, but if you think we need you that much, well, just leave. Steem will be successful with or without you.

As for suggestions, I think bundling up one minute videos into a longer one will help you get rid of those downvotes, or maybe keeping some of the steem you make. Most importantly, grow up.
