I just did (incognito window, vpn on) and i see several videos from creators with less than 1000 subscribers[1][2][3]. I'd say they aren't "super-creators"... In fact the 3rd one has only a handful of videos most of them with under 1000 views.
Wow, well done sir. I don't suppose you're at a location where the music mafia (a.k.a Vevo) wouldn't want their content going? I have no idea what those locations would be, just curious if maybe that's a factor.
