Best thing to do is to stop thinking about it. People downvote all the time. But some downvotes may have nothing to do with you in the first place. In some cases they're just there to negate the upvote of someone else. I have no idea what's going on in this case for the simple reason that I never heard of you until today. And that's not because I don't curate but because I'm an old fart who doesn't hear too well so I avoid any video/audio content.
