Sounds like a section soliciting and curating amateur pornographers to submit their own videos. Possibly with a revenue sharing scheme of some kind.

Honestly, if they wanted to keep the imagery, they could’ve even gone with YouTube Red Carpet. Conveys a sense of exclusivity, glamour, and premium content. It has exactly the same effect, but it distracts from the fact that “YouTube Red” just sounds like a porn site.

I think what would be more entertaining is if RedTube introduced a program called RedTube You to make fun of it. :P
